Y=25x is proportional. Unit rate is 25
The other 2 aren't because they have a y-intercept and don't cross the orgin
I believe that the answer is 3+84x is this question wants you to simplify the expression.
Answer:
11
Step-by-step explanation:
4(s-3)-4=4+8(3)
=4+24
=28
4s-12-4=28
4s-16=28
4s=28+16
4s=44
s=44/4
s=11
A•a^7 = a^8 (add the power (n=1+7=8))
