If Y varies inversely as 3X^2, determine what Y would be if X = 4 and another point on the equation is (2, 48).

Question

If Y varies inversely as 3X^2, determine what Y would be if  X  =  4 and another point on the equation is  (2,  48).

Steve · Answer

y = k/(3x^2) 48 = k/(3*4) k = 12*48 = 576 y(4) = 576/(3*16) = 12
