Division Property Of Equation .
Blank 1: If y is -5 when x is 2, that means the equation here is y = -2.5x. So, if x is 8, that makes the equation y = -2.5(8), which gives you -20.
Blank 2: If y is 3 when x is 1, the equation will be y = 3x. If x is 2, that will give you y = 3(2), which is 6.
Blank 3: If y is -7 when x is -21, the equation will be x = 3y. If y is 9, that will give you x = 3(9), which is 27.
Blank 4: If y is 5 when x is 4, the equation will be y = 1.25x. If y is 18, that makes the equation 18 = 1.25x, which is 14.4.

Answer:
![\implies V=\pi r^2(h-4 r)](https://tex.z-dn.net/?f=%5Cimplies%20V%3D%5Cpi%20r%5E2%28h-4%20r%29)
Step-by-step explanation:
Volume of the canister LESS the volume of 3 tennis balls:
![V=\pi r^2h-3\left(\dfrac43\pi r^3\right)](https://tex.z-dn.net/?f=V%3D%5Cpi%20r%5E2h-3%5Cleft%28%5Cdfrac43%5Cpi%20r%5E3%5Cright%29)
Expand brackets:
![\implies V=\pi r^2h-4\pi r^3](https://tex.z-dn.net/?f=%5Cimplies%20V%3D%5Cpi%20r%5E2h-4%5Cpi%20r%5E3)
Factor:
![\implies V=\pi r^2(h-4 r)](https://tex.z-dn.net/?f=%5Cimplies%20V%3D%5Cpi%20r%5E2%28h-4%20r%29)
