Question

x varies directly with x.If x = 2 and y = 8,find the constant of variation.(show and explain the solution)

Answer 1

is ur question properly put????

Answer 2

sorry the question should be x varies directly with y.If x = 2 and y = 8,find the constant of variation.(show and explain the solution)

Answer 3

y=k*x
input data x=2 and y=8
8=k*2
k=4
so y=4x

Answer 4

there is not any k in the question, how u got the answer ?????

Answer 5

We know that x varies directly with y.
y = k x, where k is just some constant.
Plug in x = 2 and y = 8
8 = 2 k
k = 4.
Hence y = 4x (QED)

Answer 6

thanksss
