Question

Select the correct answer. In which table does y vary inversely with x?

Answer 1

Answer:  C

Step-by-step explanation:

Varies inversely means xy = k

A. 1(-3) = -3

   2(-9) = -18

                     -3 ≠ -18

B. 1(-6) = -6

   2(-12) = -24

                    -6 ≠ -24

C. 1(6) = 6

   2(3) = 6

   3(2) = 6

                6 = 6 = 6      This works!

D. 1(-3) = -3

   2(2) = 4

               -3 ≠ 4

The only table that has the same k-value is option C.
