Question

find variation constant and equation of variation where y varies directly as x and y=12 when x=3.
variation constant for k=3
equation of variation is y=4x?

Answer 1

wait is k=4?

Answer 2

y=kx
12=3k
12/3 = k
k = 4
y = 4x

Answer 3

direct variation is y = kx

yes k = 4

Answer 4

ok i just seen my mistake, easy to make when doing simple math.

Answer 5

thanks
