Question

let y varies directly as x. If y =12 when x=4, then write a linear equation . what is the value of y when x=5

Answer 1

hey mate

your answer  is

y Varies directly as x, the eqaution will be in form of

y = kx, where k is constant of proportionality.

Putting y = 12 and x = 4, we get

=> 12 = 4k

=> k = 12/4

=> k = 3

So, y = 3x

Linear Equation : y - 3x = 0

When x = 5

y - 3*5 = 0

=> y = 15

thank uhh

Answer 2

The linear equation..Y=mx+c .. ya .. Y=mx m =12/4 ..M=3 .. then..

Y=15
