Try to understand the problem and take everything step by step
1. distribute the parentheses.
-3=12y-10y+35
2. Move the constants to the other side
-3-35=12y-10y
3. Subtract the terms
-38=2y
4. Divide by 2 to get y by itself
y=-19
It’s -4 because it’s a negative slope first of all cause it’s going down, second you can see it goes down 4 then right 1 so the answer would be -4 :)
Volume = Length x Length x Length
Volume :
(x + 2) (x + 2) (x + 2)
= (x² + 4x + 4)(x + 2)
= x³ + 2x² + 4x² + 8x + 4x + 8
= x³ + 6x² + 12x + 8
Answer: x³ + 6x² + 12x + 8
Yes it’s a function bc if u graph it no two points are on the same x or y point so it passes the vertical line test making it a function
