Question

What is the value of the constant of variation when y varies inversely as x and the following are true y = 5 and x = 2?​

Answer 1

k = 10

Explanation:

given 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 that y = 5 when x = 2

5 =
`(k)/(2)` ( multiply both sides by 2 )

10 = k
