Answer:
Do the graph Then Solve for y
Answer:
1. Yes, a graph of this relationship will be linear.
2. The y-intercept of the graph is (0, 2).
Step-by-step explanation:
1. The equation will be linear because it can be written in the standard form for the equation of a line. The standard form for the equation of a line is Ax + By = C. Eight can be subtracted from both sides of the equation to get 3x - 4y = -8, which fits the format for standard form. A, B, and C are integers, which includes negative numbers, zero, and whole numbers.
2. 3x - 4y + 8 = 0
3(0) - 4y + 8 = 0
-4y + 8 = 0
-4y = -8
y = 2
-6 -5 across the x axis
The reflection of point (-6, -5) across the x-axis will give (-6, 5)
What is reflection?A reflection point occurs when a figure is constructed around a single point, known as the point of reflection or center of the figure.
Given is a point (-6, -5), we need to find the coordinates of the point when it is reflected across the x-axis,
The rule for a reflection across the x-axis -:
The rule for reflecting over the x-axis is to negate the value of the y-coordinate of each point, but leave the x-value the same.
i.e, (x, y) → (x, -y)
Therefore,
(-6, -5) → (-6, 5)
Hence, the reflection of point (-6, -5) across the x-axis will give (-6, 5)

There is a mother-daughter tea that will be attended by 20 mother-daughter pairs, including the hosts. The rules of conduct are very strict; the host mother-daughter will greet everyone, all the guest mothers will greet everyone, and all the guest daughters will greet all the mothers only. How many greetings will there be?
There will be a total of 741 greetings at the mother-daughter tea.
What is Equation?Two or more expressions with an Equal sign is called as Equation.
Let's start by counting the number of greetings between the host mother-daughter pair and the other 19 mother-daughter pairs.
Since each pair only greets once, the host pair will make 19 greetings.
Now we need to count the number of greetings between the 19 guest mothers and the other 19 mother-daughter pairs
Each of the 19 guest mothers will greet 18 other mother-daughter pairs, for a total of 19 x 18 = 342 greetings.
Finally, we need to count the number of greetings between the 19 guest daughters and the 20 mothers
Each of the 19 guest daughters will greet 20 mothers
Total is 19 x 20 = 380 greetings.
By adding all we get 741 greetings
Therefore, there will be a total of 741 greetings at the mother-daughter tea.

A farmer can buy 2 types of plant food, mix A & Mix B.
Each cubic yard of mix A contains 20 pounds of acid, 30 pounds of nitrogen & 5 pounds of potash.
Each cubic yard of mix B contains 10 pounds acid, 30 pounds nitrogen & 10 pounds potash.
The minimum monthly requirements are 460 pounds of acid, 939 pounds of nitrogren & 200 pounds of potash.
If mix A costs $25 per cubic yard & mix B costs $49 per cubic yard, how many cubic yards of each mix should the farmer meet the MINIMUM monthly requirements?
Fill in the blank: If mix A costs $25 per cubic yard and mix B costs $40 per cubic yard, the farmer should blend _ yd of mix A & _ yd of mix B to meet the minimum monthly requirements at a minimum cost.
Answer:
Let's call the number of cubic yards of mix A that the farmer buys "x", and the number of cubic yards of mix B that the farmer buys "y".
We can write the following constraints based on the minimum monthly requirements:
20x + 10y >= 460 (for acid)
30x + 30y >= 939 (for nitrogen)
5x + 10y >= 200 (for potash)
We also want to minimize the cost, which is given by 25x + 49y.
This is a linear programming problem, which can be solved using simplex method or the graphical method.
By using the graphical method, we find that the optimal solution occurs at x = 11.75 and y = 4.5. This means that the farmer should buy 11.75 cubic yards of mix A and 4.5 cubic yards of mix B to meet the minimum monthly requirements at a minimum cost.
So, the answer to the question is: If mix A costs $25 per cubic yard and mix B costs $40 per cubic yard, the farmer should blend 11.75 yd of mix A & 4.5 yd of mix B to meet the minimum monthly requirements at a minimum cost.

How much money should you invest now to have $5000 in 12 years if you invest at a rate of 9.6% compounded semiannually?
just confusing can someone help due today
Step-by-step explanation:
It's a long answer. You have to find the area of the large triangle, the small triangle than subtract the two
A = 1/2(b)(h)
For the big triangle
A = 1/2(16)(4) = 1/2(64) = 32
For the small triangle
A = 1/2(8)(2)
We use 8 and 2 because that's half of 16 and 4, since at the bottom it says A and B are midpoints
A = 1/2(8)(2) = 1/2(16) = 8
Now we subtract
32-8 = 24 units
A one of a kind necklace is worth $3200. The value of the necklace increases by 9% each year. Which explicit and recursive formulas can be used to model the situation.
The fomulas of the sequence are a(n) = 3200(1.09)^n-1 and a(n) = a(n - 1) * 1.09
How to determine the fomulas of the sequencefrom the question, we have the following parameters that can be used in our computation:
First term, a = 3200
Increment, r = 9%
To find the explicit formula, we can use the formula for compound interest:
a(n) = a * (1 + r)^n-1
So, we have
a(n) = 3200(1.09)^n-1
For the recursive formula, we have
a(n) = a(n - 1) * 1.09
This is because the product of the current term and the incremnt rate gives the next term

A textbook store sold a combined total of 426 math and sociology textbooks in a week. The number of math textbooks sold was 46 more than the number of sociology textbooks sold. How many textbooks of each type were sold?
Answer:
The number of books sold were:
Math textbooks: 426
Sociology textbooks = 46
Step-by-step explanation:
Let us use the variable [tex]m[/tex] to represent the number of math books sold
Let us use the variable [tex]s[/tex] to represent the number of math books sold
Combined total of 426 math and sociology books were sold is represented by the equation:

Number of math books sold was 46 more than the number of sociology textbooks sold is given by
[tex]m - s = 46\quad\quad\quad(2)[/tex]
Adding the equations (1) + (2):
[tex](m + s) + (m - s) = 426 + 46\\\\2m = 472\\\\m = \dfrac{472}{2}\\\\m = 236\\\\[/tex]
Using Equation (1): [tex]m + s = 426[/tex] we get

five times the sum of a number and two is nineteen less than six times the number.
Answer:
The number is 29.
Step-by-step explanation:
"five times the sum of a number and two" can be represented as 5(x + 2), where x is the number. "nineteen less than six times the number" is the same as 6x - 19. The word "is" determines that these two parts are equal. So, 5(x + 2) = 6x - 19.
Solve:
5x + 10 = 6x - 19
10 = x - 19
x = 29
Check:
5 * (29 + 2) = 5 * 31 = 155
(6 * 29) - 19 = 155
155 = 155

4) Tyler is sitting at a corner of an 80 ft. by 40 ft. pool. Stretched diagonally across the pool
opposite Tyler is his friend Jason. How far must Tyler swim to reach Jason?
Answer:
Step-by-step explanation:
To find the distance Tyler needs to swim, we can use the Pythagorean theorem. The theorem states that in a right triangle, the sum of the squares of the lengths of the two shorter sides is equal to the square of the length of the longest side, which is the hypotenuse.
In this case, the two shorter sides of the triangle are 40 feet and 80 feet, and the hypotenuse is the distance Tyler needs to swim to reach Jason. So we can write the equation as follows:
40^2 + 80^2 = d^2
where d is the distance Tyler needs to swim.
Expanding the equation:
1600 + 6400 = d^2
8000 = d^2
Taking the square root of both sides:
d = sqrt(8000) = 80 * sqrt(2)
So, Tyler needs to swim a distance of 80 * sqrt(2) feet, or approximately 113.1 feet, to reach Jason.

Suppose that initially Glacier uses 1 million hours of labor per week to produce shorts and 3 million hours per week to produce almonds, while Sequoia uses 3 million hours of labor per week to produce shorts and 1 million hours per week to produce almonds. As a result, Glacier produces 8 million pairs of shorts and 48 million pounds of almonds, and Sequoia produces 15 million pairs of shorts and 20 million pounds of almonds. Assume there are no other countries willing to engage in trade, so, in the absence of trade between these two countries, each country consumes the amount of shorts and almonds it produces.
In the absence of trade between Glacier and Sequoia, Glacier would consume 8 million pairs of shorts and 48 million pounds of almonds, and Sequoia would consume 15 million pairs of shorts and 20 million pounds of almonds. However, if both countries decide to engage in trade, Glacier could specialize in producing shorts, using 1 million hours of labor per week, and Sequoia could specialize in producing almonds, using 1 million hours of labor per week. This specialization would result in Glacier producing 12 million pairs of shorts and Sequoia producing 24 million pounds of almonds. This would enable each country to consume more of both goods than they could produce in the absence of trade.

A man walks due west for 4km. he then changes direction and walks on a bearing of 197° until he is southwest of his starting point.How far is he then from his starting point?
To find the distance between the man's starting point and his final position, we can use vector addition.
Let's call the man's starting point A and his final position B. We can represent the two legs of his journey as vectors A and B, respectively.
The first leg of his journey, due west, can be represented as a vector of magnitude 4 km in the -x direction.
The second leg of his journey, on a bearing of 197°, can be represented as a vector in the -x and -y direction. We can use trigonometry to find the components of this vector.
The x component of the vector can be found using the formula:
x = magnitude * cos(angle) = d * cos(197°)
The y component of the vector can be found using the formula:
y = magnitude * sin(angle) = d * sin(197°)
where d is the magnitude of the vector (the distance the man traveled in this leg of his journey).
To find the magnitude of the vector, we'll use the Pythagorean theorem:
d^2 = x^2 + y^2
We can substitute the x and y components we found above into this equation to find d:
d^2 = (d * cos(197°))^2 + (d * sin(197°))^2
d^2 = d^2 * (cos^2(197°) + sin^2(197°))
d^2 = d^2
d = sqrt(d^2) = sqrt(d^2)
So the magnitude of the vector is d.
Next, we can add the two vectors to find the total distance from the man's starting point to his final position:
distance = sqrt((4 - d * cos(197°))^2 + (d * sin(197°))^2)
This is the distance the man is from his starting point. To find the exact value, we would need to know the value of d. However, without that information, this is as far as we can take the calculation.

Answer:
[tex]sin(P)=\frac{\sqrt{55}}{10}[/tex]
Step-by-step explanation:
Sine Function:The sine function is defined as a ratio of sides: [tex]sin(\theta)=\frac{\text{opposite}}{\text{hypotenuse}}[/tex]
where the "opposite" side is quite literally the opposite side, if you went straight from the angle, whatever side it's pointing towards is the opposite angle. The hypotenuse... is as the name implies, the hypotenuse. The symbol inside the parenthesis next to the sine is called theta and is just used to represent some angle.
We of course don't know the hypotenuse as it's not given, but we can use the Pythagorean Theorem to solve for the hypotenuse:
[tex]c^2=\sqrt{45}^2+\sqrt{55}^2\\c^2=45+55\\c^2=100\\c=10[/tex]
We do know the opposite side though, it's just the square root of 55, it's directly opposite of the angle P. Plugging in known values we get the following: [tex]sin(P)=\frac{\sqrt{55}}{10}[/tex] and we can't simplify this any further as 45 has no factors which are perfect squares.

The value of x in the given equation using laws of exponents is; x = -9
How to use laws of exponents?We want to solve the problem correctly expressed as;
3^(4x) = 27^(x - 3)
Now, some of the laws of exponents are;
1) Product of powers rule.
2) Quotient of powers rule.
3) Power of a power rule.
4) Power of a product rule.
5) Power of a quotient rule.
6) Zero power rule.
7) Negative exponent rule.
Now, 27^(x - 3) can also be expressed as;
3^(3(x - 3))
Now, according to power of power rule, if a base raised to a power is being raised to another power, the exponents are multiplied and the base remains the same. Thus;
3^(3(x - 3)) = 3^(3x - 9)
Thus, we now have;
3^(4x) = 3^(3x - 9)
