Slope intercept form: y=-2/3x+490
the slope: -2/3
y intercept: (0, 490)
function notation: f(x)=-2/3x+490
Graph: (0,495) & (735,0)
Solve:

We need to isolate k, so multiply both sides by the denominator, which is 64. When we do that, the fraction will cancel and we get:

If you want to check, plug in your answer to the original equation and see if it is true:

Answer:
14,130 cm³
Step-by-step explanation:
V = 4/3πr³
= 4/3 x 3.14 x 15 x 15 x 15
= 20 x 225 x 3.14
= 706.5 x 20
= 14,130 cm³
