6r + 7 = 13 + 7r
6r + 7 - 7r = 13
6r - 7r = 13 - 7
-r = 6
r = -6

13 - 14x = 1 - x
13 = 1 - x + 14x
13 - 1 = -x + 14x
12 = 13x
x = 12/13

2(x+7) + x = -20
2x + 14 + x = -20
2x + x = -20 - 14
3x = -34
x = -34/3

-8 - x = x - 4x
-8 = x - 4x + x
-8 = -2x
x = 4

If f(x) = 4x + 8 and g(x) = (x+4,<br> what is (fºg)(12)?

Answer:

72

Step-by-step explanation:

$f(x) = 4x+8\\g(x) = x + 4\\\\1. f(g(x)) = 4(x+4) + 8\\2. f(g(x)) = 4x + 16 + 8\\3. f(g(x))=4x + 24\\\\4. f(g(12)) = 4(12) + 24\\5. f(g(12)) = 48 + 24 = 72\\$

To do these, you have to place the entire function inside the parent function's variables.

You are inputting the value of the function g(x) into f(x)
