Yvaries directly as the square of x. if y is 25 when x is 3 find y when x is 2

y =

Step-by-step explanation:

given y varies as the square of x then the equation relating them is

y = kx² ← k is the constant of variation

to find k use the given condition y = 25 when x = 3

k = =

⇒ y = x²

when x = 2

y = × 4 =

step-by-step explanation: step 3 should really go to step seven, but anyway never mind.
