Question

Please Help!
What is the difference of t and v?
t(x)=7x-2 v(x)=x-9
A. (t-v)(x)=-6x-11
B. (t-v)(x)=-6x-7
C. (t-v)(x)=6x+7
D. (t-v)(x)=6x-11

Answer 1

B

Answer 2

\(7x -2 - (x - 9)\)

`The invisible 1`
\(7x -2 - \color{red}{1} (x - 9)\)

`Distribute -1`
\(7x - 2 - x + 9\)

\(\large \text{Combine like terms}\)
\((7x - x) + (-2 + 9)\)
\(6x + 7\)
