F(x)=3x+5 which function represents the inverse of function below

Step-by-step explanation:

Swap x and y variables

In the inverse function, you swap the x and y values.

So in the function y = 3x + 5, switch the places of the x and y variables to get

x = 3y + 5

Rearrange equation

Now rearrange this equation so that y is by itself

x = 3y + 5

3y = x - 5

y =

Final equation

The inverse function would be

7

step-by-step explanation:

i'm assuming you need to figure out how many campers go into each tent.

i got the answer by:

24+4=28

28/4=7  

36 girls

step-by-step explanation:

the 48 boys is 4 parts of the ratio

divide 48 by 4 to obtain one part of the ratio

= 12 ← 1 part of the ratio

3 parts = 3 × 12 = 36 ← number of girls
