2^12x-10
Explanation: (the picture)
Answer:
It's a perfect cube, but not a perfect square.
Step-by-step explanation:
2^3 = 8, meaning 8 is a perfect cube. But since 2^2 = 4 and 3^2 = 9, and 8 is in between, 8 is not a perfect square.
I hope this helped.
I figured out the first question, the second one in lost on.

Factor both of the equations, numerator and denominator

Cancel the like factors *excuse the zero im just showing you*

Combine frunctions

x-9=0
x+7=0
Restrictions are 9 and -7
Answer:
45
Step-by-step explanation:
you can see that the time increases by 10.
ex: 5+10=15, 15+10=25.
So, 35 + 10 = 45
The formula to find slope it (y2-y1)/(x2-x1)
(2,4) is the first point
(6,2) is the second point
(2-4)/(6-2)
-2/4 which can be simplified to -1/2
Hope this helps
