Answer:
y =20
Step-by-step explanation:
you have to get the y by itself so what you do on one side you do to the other. subtract 12 on both sides and you get y=20
Answer:
A table that has (0,0), (-1,1), (-4, 2) and undefined for any positive x value
Step-by-step explanation:
Reflecting across the y axis just changes the x values, it makes them negative. so
has points (0,0), (1,1), (4, 2) and so on. reflecting over the y axis makes them(0,0), (-1,1), (-4, 2) and again so on.
Also good to mention in
negative x values are undefined, so flipped over the y axis positive x values are undefined.
As for the answer it doesn't look like any of those shown. The first one is close, but the x values would need to swap their signs.
