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

vladimir2022 [97]

Answer: C

<u>Step-by-step explanation:</u>

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.
