Answer 1

8. yes; 18

9. no

10. no

11. yes; -9

Explanation:

The equation for inverse variation is y = k/x. The constant k will be the product of x and y: k = xy.

8.

Products are (-3)(-6) = (2)(9) = (4.5)(4) = 18.

Inverse variation with k = 18.

9.

Products are ...

(5)(4) ≠ (10)(8).

Not inverse variation.

10.

Products are ...

(2)(25) ≠ (2.5)(16).

Not inverse variation.

11.

Products are (3)(-3) = (9)(-1) = (12)(-.75) = -9.

Inverse variation with k = -9.
