Answer:

D. (x + 7, y - 2)

Step-by-step explanation:

To get back the original after translating left 7 and up 2, you must translate right 7 and down 2. The transformation of choice D does that.

Solve for the following system by using Elimination4x-2y=86x+6y=30

Ilia_Sergeevich [38]

System

$\begin{gathered} 4x-2y=8 \\ 6x+6y=30 \end{gathered}$ $\begin{gathered} 3(4x-2y)=8 \\ 6x+6y=30 \\ \\ 12x-6y=24 \\ + \\ 6x+6y=30 \\ \\ 12x+6x-6y+6y=24+30 \\ 18x=54 \\ x=3 \end{gathered}$

Now, for y

$\begin{gathered} 4x-2y=8 \\ -2y=8-4x \\ 2y=4x-8 \\ y=\frac{4x-8}{2} \\ y=\frac{4\cdot3-8}{2} \\ y=\frac{12-8}{2} \\ y=\frac{4}{2} \\ y=2 \end{gathered}$
