Question

Suppose that a and b vary inversely and that b=5/3 when a = 9. Write a function that models the inverse variation and find b when a = 10.

Answer 1

b = A/a A constant
5/3 = A/9 therefore A = 15
b = 15/a

Answer 2

b=15/15?

Answer 3

at a = 15

Answer 4

b = 15/10 = 3/2

Answer 5

Nevermind, I was just confused, Thank You

Answer 6

The result of equation should determine choice.
