Answer:
mathematical relationship between two variables that can be expressed by an equation in which one variable is equal to a constant times the other.
8 - direct variation Since the equation can be written in the form y=kx. , y varies directly with x and k. The constant of variation, k, is 3.25
9 - When solving for y, y=5x-9 so y doesn't vary directly with x.
y doesn't vary directly with x
10 - direct variation Since the equation can be written in the form y=kx, y varies directly with x and k. The constant of variation, k, is -2.4

You could factor a 7 out of 7 + 14 to get 7(1 + 2).
This would equal the same thing as 7 + 14, which is 21.
7 * 3 = 21.
21 can be factored like so:
1 * 21 = 21
3 * 7 = 21
Answer:
6y-2y^2-6
Step-by-step explanation:
3y^2 +4y-5-(5y^2 -2y+1)
3y^2 +4y-5-5y^2 +2y-1
3y^2-5y^2 + 4y+2y-5-1
-2y^2+6y-6
6y-2y^2-6
