y=kx^2
hence k=198/36.
now y=198/36*(2)^2
y=22
x = 24

y = cx when x = 8, y = 12 so that 12 = 8c which gives c = 12/8 = 1.5
y is 12
No

y = -5
y = 10x
4x= y
Find an equation of variation where y varies directly as x. One pair of values is y = 80 when x = 40
What is y? Fx varies with x, but y could be anything.
y = 8
Since r varies directly with s, we have r = ks (replace k with 5 and s with 7) r = (5)(7) r = 35
m = 24
x = 24
y = 3x y = 3*19 = 57
