Solve the problem involving direct or inverse variation. -If x varies inversely as y², and x = 3 when y = 15, find x when y = 3. A) x = 45 B) x = 27 C) x = 75 D) x = 5

Quizplus · Accepted Answer

Since x varies inversely as y^2, we have x = k/y^2 for some constant k. Given x = 3 when y = 15, we find k = 3 * 15^2 = 675. When y = 3, x = 675/3^2 = 675/9 = 75.
