B)y = 21
C)y = 15
D)y = 105

Question

Quizplus · Accepted Answer

The relationship between y and x is given as $y = kx^2$, where k is the constant of variation. When x = 3, y = 63, so we can solve for k: $63 = k(3)^2$, which gives $k = 7$. To find y when x = 5, substitute x = 5 and k = 7 into the equation: $y = 7(5)^2 = 7 \times 25 = 175$.
