First make the graph of the functions, then if the two graphs are symmetric with respect to the line y = x (mirror images over y = x ), then they are inverse functions.
Symmetric
A figure or shape that can be divided into two equal parts by a line is called symmetric figures.

The inverse function of a function f is a function that undoes the operation of f. The inverse of f exists if and only if f is bijective, and if it exists, is denoted by F^-1.

Find the x- and y-intercepts of the graph of -2x + 3y = 34. State each answer as an integer or an improper fraction in simplest form.
Answers
The x and y-intercept are the point at which graph cuts the respective axis thus the x-intercept of -2x + 3y = 34 is (-17,0) while y-intercept is (0,34/3).
What is a graph?A graph is a diametrical representation of any function between the dependent and independent variables.
The graph is easy to understand the behavior of the graph.
As per the given graph,
-2x + 3y = 34
The x-intercept is the point on the x-axis where the function cuts and since at the x-axis the value of y is 0 thus its coordinate will be (x,0).
Substitute y = 0 into -2x + 3y = 34
-2x + 0 = 34 ⇒ x = -17 so coordinate (-17,0)
Similarly y-intercept (0,y)
0 + 3y = 34 ⇒ y = 34/3 so coordinate (0,34/3)
Hence "The x and y-intercept are the point at which graph cuts the respective axis thus the x-intercept of -2x + 3y = 34 is (-17,0) while y-intercept is (0,34/3)".

Leah had $500 to spend shopping at the mall. She saw some clothes and shoes she liked and spent $345. She also wants to buy some video games for her younger brother, they are on sale for $20 each, including tax. Enter the maximum number of video games Leah can buy with the remaining money. _ (explain)
Answers
Answer:
To determine the maximum number of video games Leah can buy with the remaining money, we need to first calculate how much money she has left after buying the clothes and shoes.
Amount spent on clothes and shoes = $345
Amount left to spend = $500 - $345 = $155
Next, we need to determine the cost of each video game, including tax. If the sale price of each video game is $20, including tax, then we can assume that the actual price of each game before tax is less than $20. Let's assume that the actual price before tax is x. Then, if tax is added at a rate of t (where t is a decimal), the total price of the game including tax is:
Total price = x + t*x = x(1+t)
If the total price is $20, we can solve for x:
x(1+t) = $20
x = $20/(1+t)
We don't know the tax rate, but we can assume that it is a percentage of the actual price, and therefore less than 100%. Let's assume a tax rate of 10%, or t = 0.1. Then:
x = $20/(1+0.1) = $18.18
So each game costs $18.18 before tax.
Now we can calculate how many games Leah can buy with her remaining money:
Number of games = Amount left to spend / (Price per game + Tax per game)
= $155 / ($18.18 + 0.1*$18.18)
= $155 / $19.99
≈ 7.75
Since Leah cannot buy a fraction of a game, she can buy a maximum of 7 video games with the remaining money.

Question 1 Linearize f(x)= ³√x+1 when x=7
Answers
The linear approximation of f(x) = ³√(x+1) at x = 7 is given by y = (1/12)(x - 7) + 2.
To linearize the function f(x) = ³√(x+1) at x = 7, we can use a technique called linear approximation. The linear approximation of a function at a given point involves finding the equation of the tangent line to the graph of the function at that point.
First, let's find the derivative of f(x) = ³√(x+1). We can use the chain rule to differentiate this function:
f'(x) = (1/3)(x+1)^(-2/3)
Next, we evaluate f'(7) to find the slope of the tangent line at x = 7:
f'(7) = (1/3)(7+1)^(-2/3)
= (1/3)(8)^(-2/3)
= 1/12
Now, we have the slope of the tangent line, which is 1/12. Using the point-slope form of a line, we can write the equation of the tangent line:
y - f(7) = f'(7)(x - 7)
To find f(7), substitute x = 7 into the original function:
f(7) = ³√(7+1)
= ³√8
= 2
Substituting f(7) = 2 and f'(7) = 1/12 into the equation of the tangent line, we get:
y - 2 = (1/12)(x - 7)
Rearranging the equation, we can linearize f(x) at x = 7:
y = (1/12)(x - 7) + 2
Therefore, the linear approximation of f(x) = ³√(x+1) at x = 7 is given by y = (1/12)(x - 7) + 2.

Suppose we have a continuous random variable X with probability density function f(x) and cumulative distribution function F(x). Which of the following statements must be true?
Select all that apply:
0 ≤ F(x) ≤ 1.
F(x) = 1 for at least one value of x.
F(x)= 1 for all values of x > a, where a is a constant.
F(x) = f(x).
Answers
The statements that must be true are 0 ≤ F(x) ≤ 1 and F(x) = 1 for at least one value of x. The statements that are false are F(x)= 1 for all values of x > a, where a is a constant, and F(x) = f(x).
0 ≤ F(x) ≤ 1: This statement is true because the cumulative distribution function is a non-decreasing function. This means that the cumulative distribution function can never decrease, so the value of F(x) can never be negative, and it can never be greater than 1.
F(x) = 1 for at least one value of x: This statement is true because the cumulative distribution function is the probability that the random variable is less than or equal to the given value of x. As the random variable can take on any value, there must be at least one value of x for which the probability that the random variable is less than or equal to x is 1.
F(x)= 1 for all values of x > a, where a is a constant: This statement is false because the cumulative distribution function is a non-decreasing function, so the value of F(x) will increase as x increases. Therefore, the value of F(x) will not be 1 for all values of x greater than a.
F(x) = f(x): This statement is false because the cumulative distribution function is the integral of the probability density function. Therefore, the cumulative distribution function is not equal to the probability density function.
The statements that must be true are 0 ≤ F(x) ≤ 1 and F(x) = 1 for at least one value of x. The statements that are false are F(x)= 1 for all values of x > a, where a is a constant, and F(x) = f(x).

Conversely, if the confidence interval includes the null hypothesis value, then the two-sided significance test will fail to reject the null hypothesis at the 10% significance level. This is because the confidence interval provides a range of plausible values for the true population parameter, and if the null hypothesis value is not within this range, then it is unlikely to be true, leading to rejection of the null hypothesis.

See below:
Step-by-step explanation:
Hello! My name is Galaxy and I will be helping you today! I hope you are having a nice day.
To solve this problem, we can do it in one step with the help of one theory. I'll start off with that below.
If we have been given a few equations in the form of \(y=mx+b\), we know that \(b\) is the y intercept. Therefore, for the first equation that you have shown, \(a(x)=-x-1\) the y intercept would be \((0,-1)\).
Now that we know this, we can find the intercepts of them both and see which one is greater.
\(a(x)=-x-1\)
Based on the theorem we saw before, the y intercept for this is (0,-1).
\(b(x)=2^x -3\)
With the same theorem above, we know the y intercept for this is (0.-3)
Therefore, \(-1>-3\) so we would get our answer.
We know that (0,-1) is higher than (0,-3). Therefore, your answer would be A.

angle 1 + angle 2 + angle 3 = 180°Inserting our 2 angles into the expression gives:

a. An exponential model that predicts the number of cases t

Exponential Growth:When a quantity grows at a constantly increasing rate, we can represent it using the exponential growth function. It is represented as the expression \(ab^x\).
Where:
a is the initial value.
b is the growth factor.
The given information is:
It is given that cases were increasing by 4% each day and there were 1804 cases on April 1, 2023 We need to find the exponential model to predict the number of cases and the number of cases on April 29, 2003Take y to be SARS cases and t to be time in days since April 1, 2003
The exponential growth will be \(y = ab^t\)
So, on April 1, 2003:
1804 = \(ab^0\)
a = 1804
Cases are increasing at 4% each day.
So, cases after 1 day are:
4% of 1804 + 1804 = 72.16+1804
= 1876.16
Thus, 1876.16 = 1804\(b^1\)
\(b=\frac{1876.16}{1804}\)
b = 1.04
Thus the exponential growth is given by:
\(y = 1804(1.04)^t\)
On April 29, 2003, there will be 28 days.
So, the number of cases on April 29, 2003
\(y = 1804(1.04)^2^8\)
≈ 1804(3)
