The y intercept of the inverse function of f(x) = 3/4 x + 12 is -16, option A is correct.
To find the y-intercept of f⁻¹(x), we can start by finding the inverse function f⁻¹(x) first.
Let y = f(x) = 3/4 x + 12
To find f⁻¹(x), we can first swap x and y, and then solve for y:
x = 3/4 y + 12
x - 12 = 3/4 y
4/3 (x - 12) = y
Therefore, f⁻¹(x) = 4/3 (x - 12)
The y-intercept of f⁻¹(x) is the value of f⁻¹(x) when x = 0.
f⁻¹(0) = 4/3 (0 - 12)
= -16
Hence, the y intercept of the inverse function of f(x) = 3/4 x + 12 is -16, option A is correct.

Given the functions f(x), g(x), and h(x) shown below; list the functions from greatest to least by average rate of
change over the intervall
Answer:
f(x) > h(x) > g(x)
Step-by-step explanation:
For the average rate of change of a function between x = a and x = b,
Average rate of change = [tex]\frac{f(b)-f(a)}{b-a}[/tex]
From the table given,
Average rate of change of function 'f' between x = 1 and x = 3,
Average rate of change = [tex]\frac{f(3)-f(1)}{3-1}[/tex]
= [tex]\frac{15-7}{3-1}[/tex]
= 4
For the function 'g',
g(x) = 2x² - 18x
Average rate of change = [tex]\frac{g(3)-g(1)}{3-1}[/tex]
g(3) = 2(3)²- 18(3)
= 18 - 54
= -36
g(1) = 2(1)² - 18(1)
= 2 - 18
= -16
Therefore average rate of change = [tex]\frac{-36+16}{3-1}[/tex]
= -10
From the graph attached,
Average rate of change of the graph between x = 1 and x = 3,
Average rate of change = [tex]\frac{h(3)-h(1)}{3-1}[/tex]
h(3) = 7.5 [Although the graph is not clear]
h(1) = 2
Average rate of change = [tex]\frac{7.5-2}{3-1}[/tex]
= 2.75
Therefore, order of rate of change (from greatest to the least) for the given functions will be,
f(x) > h(x) > g(x)

2. A night with only 4 hours of sleep increases the amount of time it takes males to sprint 20 meters.
3. A post-lunch nap increases the amount of time it takes males to sprint 20 meters.
4. A post-lunch nap decreases the amount of time it takes males to sprint 20 meters.
Answer:
4. A post-lunch nap decreases the amount of time it takes males to sprint 20 meters.
Step-by-step explanation:
This question wants us to state the claim and the hypothesis.
This researchers claim can be found in the first sentence of this question.
Claim: post lunch nap decreases the time it takes to run for 20 meters.
The correct answer option for the claim is the 4th answer option. And it means that sleeping after lunch reduces the time it takes males to run in a 20m race.
B. Hypothesis
H0: Ud <= 0
H1: Ud > 0
d = is the race time without a nap - race time with a nap
A local charity held a crafts fair selling
donated, handmade items. Total
proceeds from the sale were $2,605. A
total of 89 items were sold, some at $20
each and the rest at $35 each.
Answer:
34 sold for $20
55 sold for $35
Step-by-step explanation:
20x+35y=2605
y=(98-x)
20x+35(89-x)=2605
Solve for x
20x+3115-35x=2605

Sandra rode her bike 54 miles in one day. She rode 6 times the
number of miles Caleb rode his bike. How many miles did Caleb ride
his bike? Let b represent the number of miles Caleb rode his bike.
Ab 54 - 6
B 546 = 6
C 6 = 54
Answer:
54 = 6b
Step-by-step explanation:
Sandra rode her bike 54 miles in one day.
She rode 6 times the number of miles Caleb rode his bike.
Let Caleb rode b miles. It means,
54 = 6b
We can also find b as follows :
b = (54/6)
b = 9 miles
Hence, the required equation is "54 = 6b".

find the distance between the two points rounding to the nearest tenth (if necessary)
(-7,-1) and (-4,3)
Answer:
The distance between these two points is of 5 units.
Step-by-step explanation:
Distance between two points:
Suppose that we have two points, [tex](x_1,y_1)[/tex] and [tex](x_2,y_2)[/tex]. The distance between them is given by:
[tex]D = \sqrt{(x_2-x_1)^2+(y_2-y_1)^2}[/tex]
In this question:
Distance between (-7,-1) and (-4,3). So
[tex]D = \sqrt{(-4-(-7))^2+(3-(-1))^2} = \sqrt{3^2+4^2} = \sqrt{25} = 5[/tex]
The distance between these two points is of 5 units.
