## rebecca1233 2 years ago y varies directly as the square of x. When x = 5, y = 100. Find y when x = 6. y = 105 y = 120 y = 144 y = 150

1. nubeer

$y \alpha x ^{2}$ $y=kx ^{2}$ x= 5 . y=100 plug in values and find the value of K..

2. rebecca1233

? 150?

3. nubeer

nop.. i wrote the formula above.. you just have to plug in values of x and y and find k

4. rebecca1233

i cant see what it is y = ? k ?

5. rebecca1233
