Question

9
Given m(x)= 3x - 9 and n(x)= - 4+2x, find m(x)- n(x).
Do not include spaces in your answer.

Answer 1

Step-by-step explanation:

m(x)= 3x - 9

n(x)= - 4+2x

m(x)- n(x) = 3x - 9 + 4 - 2x

= x - 5

Answer 2

Answer:

x - 5

Step-by-step explanation:

m(x) - n(x) = 3x - 9 - (-4) + 2x

m(x) - n(x) = 3x - 2x - 9 + 4

m(x) - n(x) = x - 5 ✔
