In this question, you're solving for n.

Solve for n:

-20 = -7 + 8n +3

<em>Combine like terms</em>

-20 = 8n - 4

<em>Add 4 to both sides</em>

-16 = 8n

<em>Divide both sides by 8</em>

-2 = n

Answer:

B) -2

Find the inverse of the function f(x) = 2x – 4.
kogti [31]

First  make x the subject of the relation:-

f(x) = 2x - 4

2x = f(x) + 4

x = (f(x) + 4) / 2

Now replace x by the inverse f-1(x) and f(x) by x :-

f-1(x) =  (x + 4) / 2
