Question

If y = 14 when x= 8, find y when x = 12

Answer 1

if y 14 when x=8
so 14/8=y/12
y=21

Answer 2

In the given problem, we know that y is directly proportional to x.
We also know the direct variation formula.
y = kx
Now we need to substitute the value of x and y and find out the value of k. So
14 = 8k
Then
k = 8/14
= 4/7
Now in a new equation if we put the value of K and another value of x, then we can find the value of y.
y = (4/7) * 12
= 48/7
