Question

What is the constant of variation if y varies inversely as x and y = 3 when x = 6? PLZ HELP ME I DONT UNDERSTAND

Answer 1

k = 18

Explanation:

Given that y varies inversely as x then the equation relating them is

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

To find k use the condition y = 3 when x = 6, that is

3 =
`(k)/(6)` ( multiply both sides by 6 )

18 = k

The constant of variation is k = 18
