Volume= length times width times height
<span>1.)what is the factored form of 72x-9
= 9(8x -1)
2.) expand: -3(-4y-9x)
= 12y + 27x
3.)simplify: 6(-5y+3)-25
= -30y + 18 -25
= -30y - 7
4.) write an equivalent expression for 15m-3
= 3(5m-1)
5.) simplify: 3/4 (16g-28h)-10h
= 12g - 21h - 10h
= 12g - 31h</span>
Answer:
a. Linear
A linear line is straight.
Y varies directly with x" means y = constant * x or y = kx ----- (1)1. when x = -1/2, y = 2Put it in (1):2 = k * (-1/2)multiply by 2:4 = k * (-1)4 = -kk = -4y = -4x
"find the value of y when x= -0.3"y = -4x = (-4) * (-0.3) = 1.2
So for each problem, start with y = kxThey give you one x and one y value.Put it in y = kx and find k.Then put x = -0.3 and find y.
