Step-by-step explanation:
Given that y varies inversely as x then the equation relating them is
y = ← k is the constant of variation
To find k use the condition that x = 9 when y = 15
15 = ( multiply both sides by 9 )
k = 135
y = ← equation of variation

Answer: Choice C</h3>
Explanation:
The x intercepts or roots are x = 3 and x = 5, which lead to the factors x-3 and x-5 respectively.
Multiplying out those factors gets us this:
(x-3)(x-5)
x(x-5)-3(x-5)
x^2-5x-3x+15
x^2-8x+15
