Answer:
c
Step-by-step explanation:
For an inverse function you take f(x) and turn that to y then you switch x and y. So you should start off with y= 5x -8. so then you switch x and y so x= 5y - 8. So then you solve. You subtract 8 from both sides and divide by 5 and you get F(x) inverse = x + 8/5

The total cost for four people to bowl one game is $21. Each person paid $1.50 to rent their shoes, in addition to the cost of the game, c. Which of the following equations could be used to find the value of c?
Answer: 6 + 4c = 21
Step-by-step explanation:
Answer:
4( c + $1.50 )
Step-by-step explanation:
4( c + $1.50 )
The question tells you that the total price for FOUR people is $21, and then ask about the cost PER PERSON, meaning that you need to figure out the cost of a singular person.
The question tells you that each person pays $1.50 and they also need to pay for a game, which they have given the value to be c.
So the you add those two cost together ($1.50 + c) and then multiple it by 4 as the question originally tells you that there are 4 players.

What must the missing length be for the two figures to be similar
Answer:
30
Step-by-step explanation:
First do 25/20 to get the proportional rate which is 1.25
then multiply 24 by 1.25 to get 30
The missing length PQ must be 30 for the two figures to be similar.
For two figures to be similar, their corresponding sides must have proportional lengths. Lets denote the two given quadrilaterals as PQRS and ABCD. To find the missing length PQ, we need to determine the proportional relationship between the corresponding sides of Quad PQRS and Quad ABCD.
The corresponding sides are:
PQ and AB
QR and BC
RS and CD
PS and AD
Since Quad PQRS ~ Quad ABCD, we can set up proportions for the corresponding sides:
[tex]\(\frac{{PQ}}{{AB}} = \frac{{QR}}{{BC}} = \frac{{RS}}{{CD}} = \frac{{PS}}{{AD}}\)[/tex]
Given:
QR = 25
RS = 25
AB = 24
BC = 20
DA = 28
Let's use the proportion [tex]\(\frac{{PQ}}{{AB}} = \frac{{QR}}{{BC}}\)[/tex] to find PQ:
[tex]\(\frac{{PQ}}{{24}} = \frac{{25}}{{20}}\)[/tex]
Cross-multiply to solve for PQ:
[tex]\(PQ \times 20 = 24 \times 25\)\\\\\(PQ = \frac{{24 \times 25}}{{20}}\)\\\\\(PQ = 30\)[/tex]
Therefore, PQ must be 30 for the two figures to be similar.

I used a triangle calculator I'm not really sure how to calculate it by hand. if the angle of sides 4 and 15 is set to 1 then the min is 11.33 and if the andle of sides 4 and 15 are set to 179 then the max is 18.99952
Sorry if this isnt enough, but i am sure.
Answer:
D. 11 < x < 19.
Step-by-step explanation:
The third side x is between 11 and 19 cm.
Consider sides AB (length 4) and BC (length 15) of the triangle.
Consider the angle between AB and BC is slightly less than 180 degrees. To get from point A to point C, we have to travel almost the entire length of A to C, which is from A to B and then B to C, so a bit less than 19 cm.
Consider the angle between AB and BC is slightly more than 0 degrees. To get from point A to point C, we subtract the length of AB (because we're already further along BC), so 15 - 4, a bit greater than 11.

Answer:
Table B is a function
Step-by-step explanation:
The relation shown in a table is NOT a function if the same input value gives different output values.
In Table A, input Taurus gives different outputs, so Table A is NOT a function.
In Table B, there are no repeated inputs, so Table B IS a function.

5. Select ALL of the following expressions that are linear functions (they do not need to be in slope-intercept form).
y2 = 5x +2
2x + 4 = 3x - 8
y = 3x - 2
y + x2 = 12
y = x2 + 2x
1
3x + -y = 24
Answer:
The following are the LINEAR functions.
[tex]2x\:+\:4\:=\:3x\:-\:8[/tex][tex]y = 3x - 2[/tex][tex]1[/tex][tex]3x\:+\:-y\:=\:24[/tex]Step-by-step explanation:
We know that linear functions are the equations with a straight line graph in an XY plane.
Also, a linear function is a function of the form
[tex]f(x)=mx+b[/tex]
where m is the slope and b is the y-intercept. The only power of the variable is 1.
So, from the given expressions we can determine that:
1) [tex]y^2=\:5x\:+2[/tex]
[tex]y^2=\:5x\:+2[/tex] is NOT a linear function because the power of y is 2, hence the graph won't be a straight line. Therefore, it is not a linear function
2) [tex]2x\:+\:4\:=\:3x\:-\:8[/tex]
[tex]2x\:+\:4\:=\:3x\:-\:8[/tex]
[tex]x=12[/tex]
This is a linear equation is an equation of a straight line, written in one variable. The only power of the variable is 1
3) [tex]y = 3x - 2[/tex]
[tex]y = 3x - 2[/tex] is a linear function because it is of the form [tex]f(x)=mx+b[/tex] and the power of its x and y variables is 1. Hence, the function has a straight line graph.
4) [tex]y\:+\:x^2\:=\:12[/tex]
[tex]y\:+\:x^2\:=\:12[/tex] is NOT a linear function because the power of x is 2, hence the graph won't be a straight line. Therefore, it is not a linear function.
5) [tex]y\:=\:x^2\:+\:2x[/tex]
[tex]y\:=\:x^2\:+\:2x[/tex] is NOT a linear function because the power of x is 2, hence the graph won't be a straight line. Therefore, it is not a linear function.
6) [tex]1[/tex]
[tex]1[/tex] is a constant function and a constant function is also considered linear in this context, as it is a polynomial of degree [tex]0[/tex] or is the [tex]0[/tex] polynomial.
7) [tex]3x\:+\:-y\:=\:24[/tex]
[tex]3x\:+\:-y\:=\:24[/tex] is a linear function as the power of its x and y variables is 1. Hence, the function has a straight line graph. Therefore, it is a linear function.
In a summary, the following are the LINEAR functions.
[tex]2x\:+\:4\:=\:3x\:-\:8[/tex][tex]y = 3x - 2[/tex][tex]1[/tex][tex]3x\:+\:-y\:=\:24[/tex]
