Q:

If y varies inversely with x, and the constant of variationis 4.5, what are the values missing in the table?

Accepted Solution

A:
Answer:A. 0.5B. 4.5C. 1.5D. 0.5Step-by-step explanation:y varies inversely with x can be written as:y = k/xwhere k is constant of variation.1. value of Ax=A, y = 9 and k = 4.5 (given)y = k/x 9 = 4.5/A=> A = 4.5/9=> A=0.52. Value of B x =1, y= B, k = 4.5y = k/xB = 4.5/1B= 4.53. Value of C x=C, y=3. k=4.5y = k/x3 = 4.5/C3C = 4.5C = 4.5/3C = 1.54. Value of Dx= 9, y=D, k=4.5y = k/xD = 4.5/9D = 0.5
