Question

If x varies inversely with y, y = 30 and x = 12. What is the value of the

constant of variation?

Answer 1

k = 360

Explanation:

given x varies inversely with y then the equation relating them is

x =
`(k)/(y)` ← k is the constant of variation

To find k use the condition y = 30 and x = 12 , then

12 =
`(k)/(30)` ( multiply both sides by 30 )

360 = k
