See had some cherries. Every day he ate 10 cherries and gave 5 away. After he gave that last 5 cherries away he had eaten 40 cherries altogether. How many cherries did Seb have at the start?
50 must have been his starting number of cherries.
Seb had 50 cherries at the start. This can be determined by solving the equation 10x + 5 = 40, where x is the number of days he ate 10 cherries and gave 5 away. When you solve the equation, you get x = 5, meaning he did this 5 times. Since 10x is 50, and 5 is added to that, the total is 50. Therefore, Seb had 50 cherries at the start.
To solve the equation, you first need to subtract 5 from both sides to get 10x = 35. Then, divide both sides by 10 to get x = 3.5. Since Seb could not have eaten 3.5 days worth of cherries, it means that he did the 10 and 5 activity 4 times, giving him 40 cherries before giving away the last 5. So 40 + 5 = 45 and 10x = 50, so 50 must have been his starting number of cherries.

Determine algebraically whether the function is even, odd, or neither?
f(x)=3 x 3+5
The function f(x) = 3x³ + 5 is neither even nor odd. To determine whether a function is even or odd, you need to check how the function behaves when x is replaced with -x.
To determine whether the given function is even, odd, or neither, we need to check the following conditions:
Even function: If f(-x) = f(x) for all x in the domain of f, then the function is even.
Odd function: If f(-x) = -f(x) for all x in the domain of f, then the function is odd.
Let's check these conditions for the given function:
f(x) = 3x³ + 5
f(-x) = 3(-x)³ + 5 = -3x³ + 5
f(x) = 3x³ + 5
Since f(-x) is not equal to f(x), the function is not even.
f(-x) = 3(-x)^3 + 5 = -3x^3 + 5
-f(x) = -(3x^3 + 5) = -3x^3 - 5
Since f(-x) is not equal to -f(x), the function is not odd.
Therefore, the given function is neither even nor odd.

what answer below best addresses the following statistical problem? a new advertisement for ben and jerry's ice cream introduced in late may of last year resulted in a 30% increase in ice cream sales for the following three months. does this mean that the advertisement was effective? a. yes, because an increase in sales means the advertisement worked. b. no, because the increase in sales was all caused by another variable (specifically a change in weather) c. uncertain, because there are other variables at play and correlation does not equal causation d. uncertain, because it's impossible to measure the effectiveness of advertising.
The correct answer to this statistical problem is (c) uncertain, because there are other variables at play and correlation does not equal causation.
In this scenario, we're looking at the sales of Ben and Jerry's ice cream before and after the advertisement was introduced. The sales increased by 30% for the following three months after the advertisement. So, does this mean that the advertisement was effective? The answer is not as straightforward as a simple "yes" or "no."
Option (c) acknowledges that there are other variables at play and that correlation does not equal causation.
This is the most accurate answer because it recognizes that while the increase in sales may be related to the advertisement, it's impossible to say for sure whether the advertisement was the cause of the increase in sales.
There could be other factors, such as the weather or a change in consumer preferences, that also contributed to the increase in sales.

3 of 93 of 9 questions question terry has won 18 of 35 chess games. sandra has won 24 of 36 chess games. terry wants to know how many of the remaining games she would have to win for her winning percentage to be greater than sandra's, given that sandra doesn't win any more games. let x represent the number of games remaining, and let y represent the number of games terry needs to win. which inequality represents this situation? responses 18 y35 x>2436 x 18 y35 x>2436 x 35 y18 x>2436 x 35 y18 x>2436 x 18 y35 x>36 x24 18 y35 x>36 x24 18 x35 x>2436 x
The inequality that represents this situation is y - 2x > 16.
Let's start by finding Terry's current winning percentage:
Terry's current winning percentage = 18/35 = 0.5143 (rounded to 4 decimal places)
We want to find out how many of the remaining games Terry needs to win for her winning percentage to be greater than Sandra's winning percentage, given that Sandra doesn't win any more games. Sandra's current winning percentage is:
Sandra's current winning percentage = 24/36 = 0.6667 (rounded to 4 decimal places)
Let x be the number of remaining games and y be the number of games Terry needs to win. Since there are a total of x remaining games and Terry wins y of them, she will have won a total of 18 + y games out of 35 + x games. Therefore, her winning percentage after winning y of the remaining games would be:
(18 + y) / (35 + x)
We want this winning percentage to be greater than Sandra's winning percentage:
(18 + y) / (35 + x) > 24/36
Multiplying both sides by 36(35 + x), we get:
36(18 + y) > 24(35 + x)
Simplifying the left-hand side:
36(18 + y) = 648 + 36y
Simplifying the right-hand side:
24(35 + x) = 840 + 24x
Substituting these simplifications back into the inequality, we get:
648 + 36y > 840 + 24x
Simplifying:
12y - 24x > 192
Dividing both sides by 12:
y - 2x > 16
Therefore, the inequality that represents this situation is:
y - 2x > 16
So Terry needs to win more than twice as many remaining games as the number of games Sandra has won more than her in order to have a winning percentage greater than Sandra's winning percentage.

What is Linear Equation?
A linear equation is a mathematical expression in which the highest power of the variable is 1. It can be written in the form of:
y = mx + b
where y and x are variables, m is the slope of the line, and b is the y-intercept of the line. This form is called the slope-intercept form of a linear equation.
To solve the equation 6x + 16 = 2x + 28:
Simplify both sides of the equation by combining like terms:
6x + 16 = 2x + 28
Subtract 2x from both sides:
4x + 16 = 28
Subtract 16 from both sides:
4x = 12
Solve for x by dividing both sides by 4:
4x = 12
x = 3

Answer:
x = 3/85
Step-by-step explanation:
log2 (6) - log2 (5x) = log2 ( 34)
We can use the properties of logs.
First subtract log2 (6) from each side.
log2 (6) - log2 (5x) - log2 (6) = log2 ( 34)-log2 (6)
- log2 (5x) = log2 ( 34)-log2 (6)
Now we know that log a - log b = log a/b
- log2 (5x) = log2 ( 34/6)
- log2 (5x) = log2 ( 17/3)
Multiply each side by -1
log2 (5x) = -log2 ( 17/3)
We know that -log (a/b) = log ( b/a)
log2 (5x) = log2 ( 3/17)
The terms inside the logs must be the same
5x = 3/17
Divide each side by 5
5x/5 = 3/17 * 1/5
x = 3/85
Lars, Rita and Alan regularly go swimming. Lars goes every
2 days, Rita goes every 3 days and Alan goes every 5 days.
They all went swimming together on Friday 1st June.
a) On what date will Lars and Rita next go swimming together?
b) On what date will Rita and Alan next go swimming together?
c) On what day of the week will all 3 next go swimming together?
d) Which of the 3 (if any) will go swimming on 15th June?
Part (a)
Lars goes every 2 daysRita goes every 3 daysThe LCM of 2 and 3 is 2*3 = 6.
Lars and Rita's schedule aligns every 6 days.
These two went swimming together on June 1st.
6 days later would be June 7th, which is when they swim together again. See the chart in part (d) below.
Answer: June 7th======================================================
Part (b)
Rita goes every 3 daysAlan goes every 5 days.LCM = 3*5 = 15
Add 15 days to the first of June to get 1+15 = 16. See the chart in part (d) below.
Answer: June 16th======================================================
Part (c)
The LCM of 2, 3, and 5 is 2*3*5 = 30
The trio will swim together every 30 days.
Since there are 7 days in a week, divide 30 over 7 and find the remainder.
30/7 = 4 remainder 2
We don't care about the quotient. All we focus on is the remainder.
A remainder of 2 means that we move 2 days ahead of Friday to land on Sunday. You can use a calendar to confirm that adding 30 days to the starting Friday will get you to Sunday. It doesn't matter what month you are in, so it could be June or any month really.
Answer: Sunday======================================================
Part (d)
Here's a chart when all three go swimming:

Each number refers to a day number in June, with exception to the 36 for Alan. Treat that "36" as 36-30 = 6 days beyond the end of June (aka July 6th).

Find the inverse equations for each of the functions below. Use function notation. Justify that each inverse equation works for its function.
A. g(x)= x³ - 5
B. p(x) = 2(x+3)³
C. t(x) = 10(x-4)/3
The inverse of the functions g(x), p(x), and t(x) are expressed as; g⁻¹(x) = 3√(x + 5), p⁻¹(x) = 3√(x/2) - 3, and t⁻¹(x) = (3x/10) - 3. respectively.
What is Inverse of a functionA function is said to have an inverse if it is both one-to-one and onto
we replace the functions g(x), p(x), and t(x) with y and make x the subject to arrive at the inverse g⁻¹(x), p⁻¹(x), and t⁻¹(x) as follows;
For g(x)= x³ - 5:
y = x³ - 5
y + 5 = x³ {add 5 both sides}
x = 3√(y + 5) {take cube root}
g⁻¹(x) = 3√(x + 5).
For p(x) = 2(x+3)³:
y = 2(x+3)³
y/2 = (x+3)³ {divide through by 2}
3√(y/2) = x + 3 {take cube root}
x = 3√(y/2) - 3 {subtract 3 from both sides}
p⁻¹(x) = 3√(x/2) - 3.
For t(x) = 10(x-4)/3:
y = 10(x-4)/3
3y = 10(x-4) {cross multiplication}
3y/10 = x + 3 {divide through by 10}
(3y/10) - 3 = x {subtract 3 from both sides}
t⁻¹(x) = (3x/10) - 3.
Therefore, the inverse of the functions g(x), p(x), and t(x) are derived by interchanging the value of x for y and expressed respectively as; g⁻¹(x) = 3√(x + 5), p⁻¹(x) = 3√(x/2) - 3, and t⁻¹(x) = (3x/10) - 3.

How does the graph of g(x) = (x - 2)3 + 7 compare to the parent function f(x) = x³?
The graph of g(x) = (x - 2)^3 + 7 is a transformation of the parent function f(x) = x^3.
The parent function f(x) = x^3 has a shape that is symmetrical about the origin and increases as x moves away from the origin. The graph of g(x) = (x - 2)^3 + 7 is also symmetrical about the origin, but it has been translated 2 units to the right and 7 units up from the parent function.
So, the graph of g(x) = (x - 2)^3 + 7 is similar in shape to the parent function f(x) = x^3, but it is shifted to the right and up on the coordinate plane.

Student 2 has lower percentage of likes as compare to student 1 ,it is equal to 71.5%.
Number of likes of student 1 is equal to 147
Number of likes of student 2 is equal to 42
147 > 42
⇒Number of likes of student 1 is greater than student 2
Difference between number of likes
= 147 - 42
= 105
Percentage difference = ( 105 / 147 ) × 100
= 71.5%
Student 2 has 71.5% lower percentage of likes than student 1
Therefore, student 2 has lower percentage of likes than student 1 which is equal to 71.5%.

Tessa is opening Tessa's Terrific Tees, her own custom T-shirt business. She bought a T-shirt printing machine that is currently valued at $2,200. The machine loses 1 4 of its value every year. Write an exponential equation in the form y=a(b)x that can model the value of the machine, y, x years after purchase. Use whole numbers, decimals, or simplified fractions for the values of a and b.
Answer:
y= 2200 (3/4)x
Step-by-step explanation:
You can model a real-world situation involving an initial value and a constant growth or decay factor with an exponential equation in the form y=a(b)x, where b>0 and b≠1.
The constant a represents the initial value. It is the y-value of the equation when x=0.
The constant b represents the growth or decay factor.
When the equation models exponential growth, b>1.
When the equation models exponential decay, 0<b<1.
An exponential equation in the form y=a(b)x can model the value of the machine, y, x years after purchase. To write the equation, first look for phrases in the problem that tell you about the initial value, a, and the growth or decay factor, b.

The constant a is the initial value. The initial value of the machine is $2,200. So, a=2,200.
The constant b is the decay factor, since the value of the machine is decreasing. The machine loses 1/4 of its value each year. In other words, the value of the machine each year will be 1–1/4= 3/4
times the value the year before. So, b= 3/4.
The exponential equation y= 2200 (3/4)x models the value of the machine.
An exponential equation in the form y=a(b)x that can model the value of the machine, y, x years after purchase is y= 2200*14*x
What is a linear equation?A linear equation is an equation that has the variable of the highest power of 1. The standard form of a linear equation is of the form Ax + B = 0. In mathematics, a linear equation is an equation that may be put in the form [tex]{\displaystyle a_{1}x_{1}+\ldots +a_{n}x_{n}+b=0, } where x_{1}, \ldots, x_{n} are the variables, and {\displaystyle b, a_{1}, \ldots, a_{n}}[/tex] are the coefficients, which are often real numbers.
Given that;
The cost of tshirt printing machine= $2200.
The lose of machine= 14
Now,
Substituting all the values in equation y=a(b)x
a=2200
b=14
y=2200*14*x
Therefore, the linear equation of the question will be y=2200*14*x
