Question

Y=k√x and y=7 and x=9. What is the value of y when x=36

Answer 1

y = 14

Explanation:

y = k
`√(x)` Solve for k

7 = k
`√(9)`

7 = k3 Divide both sides by 3 to solve for k

`(7)/(3)` = k

y = kx

y =
`\sqr(7)/(3) }`
`√(36)`

y =
`(7)/(3)`(6)

y = 14

`(7)/(3)`
`((6)/(1))` is the same thing as
`(7)/(1)`
`((2)/(1))` I cross canceled the 3 and the 6

`(14)/(1)` = 14
