Answer:
<h2>x = 3</h2>
Step-by-step explanation:
Look at the picture.
Therefore we have:
<em>cross multiply</em>

<em>divide both sides by 3</em>

Direct variation has this equation:
y = kx
where k is the constant of variation
y = -5 ; x = -15
y = kx
-5 = k(-15)
-5/-15 = k
1/3 = k
Choice D. y = 1/3 x
Answer: The answer is D. P(t) = - 16t^2 + 100t / 3.2808
