No way is this correct!
5-3/2-9/4=1 1/4
The answer is C.
It's the formula of the volume of a cone with equal lengths of radius and height.

Answer:
Yes ans = 27720. Total possibilities = C(4,1) * C(6,4) * C(11,6) = 27720.
Let's input the x value (5) and see if the output is correct (-1).
y = 2(5) - 11
y = 10 - 11
y = -1
(5, -1) is a solution to y = 2x - 11.
The only ordered pairs that are a solution to y = 8x are (2, 16), (1, 8), and (-3, -24).
y = 8(2)
y = 16
y = 8(1)
y = 8
y = 8(-3)
y = -24
