If y varies inversely as x^2 and y=3 when x=18, what is y when x=13

y*x² = k

(3)(18)² = k

 972 = k

**************

y*x² = k

y(13)² = 972

169y = 972

    y =

1. d.90

2. e. none of these (80)

3. a. 0

4. b. 6

5. e. none of these (10)

6. a. 5

step-by-step explanation:

if you meant, "on the way from (3, 2) to (3, 14):

x does not change; y increases by 12.
