Answer:

x=-8

Step-by-step explanation:

First you should add 5x+67 and 5x+61 together which is 10x+128

Then you set that equal to 3x+72 which would be: 10x+128=3x+72

After that subtract 3x from both sides which leaves you with: 7x+128=72

Then subtract 128 from 72 which gives you: 7x=-56

Then divide by 7 which gives you x equals negative eight

Given the following functions, find and simplify (f • g)(x) f(x)=—x+3 g(x)=-x-1

Hitman42 [59]

Answer:

$(f\circ g)(x)= x + 4$

Step-by-step explanation:

Composite Function

Given f(x) and g(x) as real functions, the composite function $(f\circ g)(x)$ is defined as:

$(f\circ g)(x)=f(g(x))$

It can be found by substituting g into f.

We are given the functions:

f(x) = -x + 3

g(x) = -x -1

Find

$(f\circ g)(x)=f(g(x))= - (-x -1) + 3$

Removing parentheses:

$(f\circ g)(x)= x + 1 + 3$

Simplifying:

$\mathbf{(f\circ g)(x)= x + 4}$
