Mathematics
1 answer:
PIT_PIT [208]3 years ago
6 0

Answer:

y = \frac{x}{8}

Step-by-step explanation:

since y varies directly as x, then the equation relating them is

y = kx ← k is the constant of variation

to find k use the given condition y = 9 when x = 72

k = \frac{9}{x} = \frac{9}{72} = \frac{1}{8}, hence

y = \frac{1}{8} × x = \frac{x}{8}

= -2x³ -x² + 12 / 3x³

The answer is C.
