The problem asks:
what is 2y+7 when y=-3?
Since y=-3 then 2y+7=2(-3)+7=-6+7=1.
Similarly, when y=-3, -4y − 10=<span>-4(-3) − 10=12-10=2.
Answer:
</span><span>2y + 7=1
-4y − 10=2</span>
4(3-7x). Since there are 4 sides in a square, you multiply one length by 4 to get the perimeter. 4(3-7x) simplifys to 12-28x.
