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

HI!

It's simple. If y = 14 when x = 8, you would divide 14 by 8, giving you 1.75. THen, you would multiply this with  12 to get your x value, 21.

Hope this helps!

Hey mate

Here's your answer

y varies directly as x:

y ~ x or can be also written as y = kx where k is a constant scalar value

given: y = 14 when x = 8

y = kx or

k = y/x = 14/8 = 7/4

k = 7/4

find x when y = 21

y = k*x

x = y/k = 21/(7/4) = 21 *4 /7 = 12

Hope it helps you!
