What’s the inverse of 4x + 12

stiks02 [169]

Answer:

1/4x -3

Step-by-step explanation:

To find the inverse of a function, exchange x and y and then solve for y

y =4x+12

Exchange x and y

x = 4y+12

Solve for y

Subtract 12 from each side

x-12 = 4y+12-12

x-12 = 4y

Divide by 4

(x-12)/4 = 4y/4

The inverse is

1/4x -3

Solve the equation V=1/3 Bh for B

ycow [4]

V=1/3Bh
multiply both sides by 3over 1
3/1V=bh
because 3/1 and 1/3 cancel out
then divide by h
so your h cancels out and your answer is
(3/1V)/h = B
