0.72(x + 2) = 7.2

x =

x = 8

Step-by-step explanation:

First, let's distribute:

Isolate x:

Divide:

answer: its c because when it has a magnet next to it it will move away from the mixture. hope this

step-by-step explanation:

since we know that the two functions are equal, f (x) = g

(x), therefore when we equate the two equations the result should be similar to

3x = x – 4:

a. f(x) = 3x, g(x) = x – 4

equating the two functions:

3x = x – 4             (correct)

so we now got our answer (a)
