For given function f(x) the y in the graph are f(2) = 4,f(0) = 3 ,f(-6) = -6 and f(4) = 5
What is function?A function is described as a relationship between a set of inputs, each of which has a single output. The simplest definition of a function is an association between inputs where each input is connected to a single, unique output. There is a codomain or range for each function. A function is frequently referred to as f(x), where x is the input.
Here,
In the given graph
when x = 2
y = 4
and x = 0
y = 3
Put it in slope formula
=> m =y2 - y1 / x2 -x1
=> m =1/2
m = 1/2
Now we can just put them into slope formula
y - y₁ = m(x - x₁)
y - 4 = 1/2(x - 2)
y = 1/2(x) -1 + 4
y = 1/2(x) + 3
Now we can just put them into slope formula
y - y₁ = m(x - x₁)
y - 3 = 1/2(x - 0)
y = 1/2(x) + 3
Thus, the function for given f(x) is solved

How do you find the domain and range of a system of inequalities?
To find the domain and range of a system of inequalities, you need to solve the system of inequalities, plot the solution, determine inequality sign for solution, shade area of solution, then the x-values of the area represent domain and y values represent range.
Solve the system of inequalities for x and y in terms of each other.
Plot the solutions on a coordinate plane. Each solution will be a boundary line for the solution set.
Determine the inequality signs for each solution. Solutions with < or > signs will be represented as a dashed line, while solutions with ≤ or ≥ signs will be represented as a solid line.
Shade the portion of the coordinate plane that satisfies all of the inequalities.
The shaded area represents the solution set for the system of inequalities.
The domain is the set of all x-values that are included in the solution set and the range is the set of all y-values that are included in the solution set.

in a certain board game, a player rolls two fair six-sided dice until the player rolls doubles (where the value on each die is the same). the probability of rolling doubles with one roll of two fair six-sided dice is 16 . what is the probability that it takes three rolls until the player rolls doubles?
The probability of rolling doubles with three rolls of two fair six-sided dice is 0.512.
How do you calculate probability?
Probability is the likelihood that something will happen. Probability is calculated by dividing the number of ways the event can occur by the total number of outcomes.
The probability of rolling doubles with one roll of two fair six-sided dice is 16/36, or 1/6. This means that the probability of not rolling doubles with a single roll is 5/6.
The probability of not rolling doubles with two rolls is (5/6)^2, or 25/36.
The probability of not rolling doubles with three rolls is (5/6)^3, or 125/216.
Therefore, the probability of rolling doubles with three rolls of two fair six-sided dice is (216-125)/216, or 91/216, or 0.512.
P(doubles on 1 roll) = 1/6
P(not doubles on 2 rolls) = (5/6)^2 = 25/36
P(not doubles on 3 rolls) = (5/6)^3 = 125/216
P(doubles on 3 rolls) = 1 - (125/216) = 91/216 = 0.512

2. Box A, Box B, and Box C contain 4,342 beads altogether. There are 18 more beads in Box B than Box A. There are 3 times as many beads in Box C as in Box B. How many beads are inside Box A?
Translate the verbal phrase into a mathematical expression.
The sum of x and n divided by 3 more than twice the product of x times y
Answer:
A. 293 dolls each
B. 710 beads
C. (n+n)/3 >2xy
Step-by-step explanation:
1. Let A be the number of dolls collected by Gelyn and B the number collected by Geraldine.
At the start:
A = 1,178, and
B = 588
Girlie gets the same number of dolls from both, which we'll say is x. The situation is then:
Gelyn: A - x
Geraldine = B - x
Girlie = 2x
After the transfer, we find that A-x = 3(B-x) [Gelyn had 3 times as many dolls left as Geraldine]
Lets rearrange this last expression:
A-x = 3(B-x)
A-x = 3B-3x
2x=3B-A
Use the values of A and B to find x:
2x=3(588)-(1,178)
2x = 586
x = 293
Gelyn and Geraldine each gave Girlie 293 dolls.
========
2. Let A, B, and C stand for the number of beads in Boxes A, B, and C, respectively. We are told that:
A + B + C = 4342 [Box A, Box B, and Box C contain 4,342 beads altogether]
and learn that:
A+18 = B, and [There are 18 more beads in Box B than Box A]
C = 3B [There are 3 times as many beads in Box C as in Box B]
How many beads in Box A?
We have three equations. Lets find a way to substitute so that we can eliminate the unknowns B and C.
Look at: A + B + C = 4342
If we can rearrange the other equations to express the variables B and C in terms of A, we could solve the problem.
A+18 = B becomes B=A+18 [We can now calculate B from A]
The second, C = 3B, does not have A, but we can use the above expression for B, which will allow C to be expressed as a function of A:
C = 3B
C = 3(A+18)
C = 3A + 64 [We can now calculate C from A]
Use these definitions of B and C in the first equation (substitution):
A + B + C = 4342
A + (A+18) + (3A + 64) = 4342
6A + 82 = 4342
6A = 4260
A = 710 Box A has 710 beads
3. The sum of x and n divided by 3 more than twice the product of x times y
(n+n)/3 [The sum of x and n divided by 3]
>2xy [more than twice the product of x times y]
Put these together:

Extending Voting Rights
Voting rights for various segments in the United States was extended in stages from the time the United States gained independence, to the late 1900s.
How have voting rights been extended in the United States ?In the late 1700s and early 1800s, voting rights were expanded to include more people, such as white men who owned property. The 15th Amendment was ratified in 1870, and prohibits the federal and state governments from denying a citizen the right to vote based on that citizen's "race, color, or previous condition of servitude."
The 19th Amendment was then ratified in 1920, and prohibits the federal and state governments from denying the right to vote to citizens of the United States on the basis of sex. Then the Voting Rights Act of 1965 was passed to overcome legal barriers at the state and local levels that denied African Americans the right to vote under the 15th Amendment. It was one of the most effective pieces of legislation passed during the Civil Rights Movement.
The 26th Amendment lowered the national voting age from 21 to 18 for all federal, state, and local elections.

What in mathematics is a curve?Curve, An abstract phrase used only to describe the trajectory of a linearly stretching point in mathematics (see continuity). Usually, an equation will create such a route. The term may also be used to describe a linear model or a collection of connected line segments. The curve is referred to as a route, or a plot line (or just arc). If a curve is the continuous injective picture of either an interval or indeed a circle, it is considered simple.

true/false. The expected result of the experiment would be for the markers to have shifted adjacently to each other. If the scientist sees no movement, the results could be interpreted as the markers were placed on plates moving similarly, which could cause little to no change in distance.
The experiment's predicted outcome is that the markers will either be farther apart or closer together, proving that the tectonic plates are in fact moving and not static.
What is probability ?The area of mathematics known as probability deals with numerical representations of the likelihood that an event will occur or that a statement is true.
An event's probability is a number between 0 and 1, where, roughly speaking, 0 denotes the event's impossibility and 1 denotes certainty.
The likelihood that an event will occur increases with its probability.
A straightforward illustration is tossing a fair (impartial) coin.
The coin is fair, thus the outcomes "heads" and "tails" are equally likely; the likelihood of "heads" is equal to the likelihood of "tails"; and because there are no other conceivable outcomes, the likelihood of either "heads" or "tails" is 1/2 (which is also an acceptable spelling).

is it possible for a data set to have no mode? group of answer choices yes, if two observations occur twice. no, unless there is an odd number of observations no, if the data set is nonempty, there is always a mode yes, if there are no observations that occur more than once.
Yes, it is possible for a data set to have no mode.
A mode is the most common value in a data set, so if there are no observations that occur more than once, the data set would have no mode. For example, a data set of the numbers {1, 2, 3, 4, 5} would have no mode because none of the numbers appear more than once.
Additionally, a dataset can also have multiple modes, or a bimodal distribution, which means that there are two or more observations that occur with the same highest frequency. A dataset can have a multimodal distribution as well if it has more than two modes.
In summary, a dataset can have no mode if no observations occur more than once, or have multiple/multimodal modes if more than one observations occur with the same highest frequency.

A polynomial f and a factor of f are given. Factor the polynomial completely using long division. Show work.
The polynomial x⁵ - 4x³ + x² - 4 will have a remainder of -8 when divided by x² - x + 1 and the result can be written in the form (x³ + x² - 4x + 4) - 8/(x² - x + 1).
How to divide the polynomialUsing the long division method will require us to; divide, multiply, subtract, bring down the next number and repeat the process to end at zero or arrive at a remainder
We shall divide the polynomial x⁵ - 4x³ + x² - 4 by x² - x + 1 as follows;
x⁵ divided by x² equals x³
x² - x + 1 multiplied by x³ equals x⁵ - x⁴ + x³
subtract x⁵ - x⁴ + x³ from x⁵ - 4x³ + x² - 4 will result to x⁴ - 5x³ + x² - 4
x⁴ divided by x² equals x²
x² - x + 1 multiplied by x² equals x⁴ - x³ + x²
subtract x⁴ - x³ + x² from x⁴ - 5x³ + x² - 4 will result to -4x³ - 4
-4x³ divided by x² equals -4x
x² - x + 1 multiplied by -4x equals -4x³ + 4x² - 4x
subtract 4x³ + 4x² - 4x from -4x³ - 4 will result to 4x² - 4x - 4
4x² divided by x² equals 4
x² - x + 1 multiplied by 4 equals 4x² - 4x - 4
subtract 4x² - 4x - 4 from 4x² - 4x - 4 will result to a remainder of -8.
Therefore, the polynomial x⁵ - 4x³ + x² - 4 divided by x² - x + 1 gives a quotient x³ + x² - 4x + 4 and a remainder of -8 and can be written as (x³ + x² - 4x + 4) - 8/(x² - x + 1).

Now , the value of A is
Let the original cost of the ticket be represented as x
Let the discounted price of the ticket be y
Now , the percentage of discount = 35 %
So , the discounted price of the ticket y = original cost of the ticket - ( 35/100 ) x original cost of the ticket
Substituting the values in the equation , we get
The discounted price of the ticket y = x - 0.35x
On simplifying the equation , we get
The discounted price of the ticket y = 0.75x
y = 0.75x be equation (1)
Now , the cost of the ticket cannot be a negative value so it should lie in the first quadrant

peters school runs a rugby team. over their first 10 games they scored a mean of 17 points per game. after their 11th game the mean had reduced to 16 points per game. how many points were scored in the 11th game?
6 points were scored in the 11th game.
What is mean ?Mean is the arithmetic average of a set of given numbers. Therefore the mean in math is often referred to as simply the average.
The mean is the total number of points scored divided by the number of games.
So if the mean is 17 points per game for the first 10 games, the total number of points scored in the first 10 games is 17 * 10 = 170.
Similarly,
if the mean is 16 points per game after the 11th game, the total number of points scored in the first 11 games is 16 * 11 = 176.
To find the number of points scored in the 11th game
we can subtract the total number of points scored in the first 10 games from the total number of points scored in the first 11 games:
176 - 170 = 6
Therefore, 6 points were scored in the 11th game.

This is the last choice on the screenshot you provided
Step-by-step explanation:
Use y to represent f(x)
[tex]y=4\sqrt[5]{x-1}+2[/tex]
Replace x with y and y with x:
[tex]x=4\sqrt[5]{y-1}+2[/tex]
Solve for y in terms of x and that will be the inverse of f(x)
Switch sides:Answer: Last choice on the screen, namely

How many solutions exist for the given equation?
1/2(x+ 12) = 4x-1
zero
one
two
O infinitely many
0.5x + 6 = 4x - 1
3.5x = 7
x = 2
Only one solution exists for the given equation.
Answer:
one
Step-by-step explanation
For a polynomial function, the number of solutions, or zeros, is generally equivalent to the highest degree. For example, a cubic function (e.g. [tex]x^3+2x^2[/tex]) has 3 real zeros (x=-2, x=0, and x=0) and a quadratic (e.g. [tex]x^2-1[/tex]) has 2 real zeros (x=-1 and x=1).
For your problem, [tex]\frac{1}{2} (x+12)=4x-1[/tex], the highest degree is 1 since this is a linear function. To prove there is only one solution, let's bring all the terms to one side, simplify, and solve for x.
Distribute the 1/2 --> [tex]\frac{1}{2} x+6=4x-1[/tex]Subtract 4x from both sides --> [tex]\frac{1}{2}x+6-4x=-1[/tex]Subtract 6 from both sides --> [tex]\frac{1}{2} x-4x=-7[/tex]Combine 1/2x and -4x --> [tex]-3.5x=-7[/tex]Divide both sides by -3.5 --> [tex]x=2[/tex]There only one solution to the equation as shown above and as can be seen in step 4, the x is only to the first degree ([tex]x=x^1[/tex]) which indicates that there is only one solution, 2.
Ben's living room is a rectangle measuring 10 yards by 192 inches.
By how many feet does the length of the room exceed the width?
First of all, we need to know what the units are in this problem.
We can see that there is yards, inches, and feet.
(Keep in mind that yd = yard, ft = feet, and in = inches)
1yd = 3ft
1ft = 12in
Let's figure out how many inches are in a yard.
If we know that 3 feet are in every yard, and 12 inches are in every foot, we can make an equation that looks like this:
(1yd × 3ft) × 12 = 36
This means that there are 36 inches in every foot.
Now that we know how many inches are in a yard, lets figure out how many inches are in 10 yards.
36 × 10 = 360
There are 360 inches in 10 yards.
Now, let's figure out how much 360 inches exceeds 192 inches.
360 - 192 = 168
To convert this to feet, we need to use an equation that looks like this:
168 ÷ 12 = 14
Therefore, the amount of feet that the length of the room exceeds the width is 14 feet.

The general solution of the given higher-order differential equation is y(x) = e2x + x2 + c4e3x + c5e-3x.
What is general solution?A general solution is an answer that can be applied to a wide range of problems. It is a broad-based approach that can be used to solve any problem, regardless of its complexity or specific details. General solutions take into account the overall goal of a problem, rather than its individual elements, and look for a way to achieve the desired result. Additionally, they are often easy to implement and can be applied to a variety of scenarios.
The general solution of the given higher-order differential equation, y(4) + y''' + y'' = 0, is given by
y(x) = c1e2x + c2e-2x + c3x2 + c4e3x + c5e-3x + c6x3.
Here, c1, c2, c3, c4, c5 and c6 are constants of integration.
To determine the values of these constants, we must use initial conditions. Suppose we are given y(0)=1 and y'(0)=2, then we can solve for the constants using this information.
Substituting y(0)=1 and y'(0)=2 into the equation, we get
1 = c1 + c2 + c3(0)2 + c4 + c5 + c6(0)3
2 = 2c3 + 3c6(0)2
Solving these equations, we get c1 = 1, c2 = 0, c3 = 1 and c6 = 0.
Therefore, the general solution of the given higher-order differential equation is
y(x) = e2x + x2 + c4e3x + c5e-3x.

a bag contains red marbles and blue marbles. zuri randomly removes marbles from the bag, one at a time and without replacement, and stops when she has removed all the red marbles from the bag. what is the expected value of the number of marbles zuri removes from the bag?
The expected value of the number of marbles Zuri removes from the bag is the sum of the number of red marbles plus the number of blue marbles.
The expected value of the number of marbles Zuri removes from the bag is the sum of the number of red and blue marbles. This is because the expected value of an event is the sum of the probability of each outcome multiplied by the associated outcome. Since Zuri is randomly removing marbles from the bag, one at a time and without replacement, the probability of each outcome (red or blue) is equal. Therefore, the expected value of the number of marbles Zuri removes from the bag is the sum of the number of red marbles plus the number of blue marbles. This is because each marble has an equal chance of being removed and, therefore, each marble has the same expected value.
