2. the figure is reflected in the y-axis
Step-by-step explanation:
1.
The given transformation moves each point horizontally to the same
distance on the other side of the y-axis. This is shown in the attachment.
2.
The given rule ...
(x, y) → (-x, y)
is the most precise description of the transformation. In English, it can be

Step-by-step explanation:
Correct me if I'm wrong
7a+21=56
Begin by subtracting 21 on both sides:
21-21=0 so the 21 in the left cancels, then 56-21=35
Your new equation will be
7a=35
Finally, divide by 7 on both sides:
7/7=1 and 35/7=5
your answer will be
a=5
Not sure but i followed the formula and that’s what came out.
