If y varies inversely as x, and y=6 when x=3. Then find the value of y when x=32
s2008m [1.1K]

Answer: y = 18/32


Step-by-step explanation: Okay the equation is xy = k

You plug in x and y.

(3)(6) = k

18 = k

To get the value of y when x = 32 you plug in 32.

Use this equation now y = k/x

Now it is y = 18/32

And that is your answer!
