Question

Please please help me with this!

Answer 1

y =
`(25)/(6)`

Explanation:

Given that y varies with x then the equation relating them is

y = kx ← k is the constant of variation

To find k use the condition y = 5 when x = 6

k =
`(y)/(x)` =
`(5)/(6)`

y =
`(5)/(6)` x ← equation of variation

When x = 5, then

y =
`(5)/(6)` × 5 =
`(5(5))/(6)` =
`(25)/(6)`
