Factor −1/3 out of −1/3x−8.

Gnom [1K]

For this case we have the following expression:

$- \frac {1} {3} x-8$

We take common factor $- \frac {1} {3}$ , for this we must take into account that:

$- * + = -\\\frac {24} {3} = 8$

So, factoring the expression we have:

$- \frac {1} {3} (x + 24)$

ANswer:

The factored expression is:

$- \frac {1} {3} (x + 24)$

What is the inverse of the function f(x)= 1/4x-12

Tasya [4]

Answer:

The inverse is 4x+48

Step-by-step explanation:

y = 1/4x - 12

Exchange x and y

Solve for y

x = 1/4y -12

Add 12 to each side

x+12 = 1/4 y -12+12

x+12 = 1/4y

Multiply each side by 4

4(x+12) = 4*1/4y

4x+48 = y

The inverse is 4x+48
