Question

Given that y varies directly with x in the table below, what is the value of y if the value of x is 7?

A. 37
B. 42
C. 48
D. 54

Answer 1

The answer is B.42
Y varies direcly with x,so,there must be an constants anon.
Let say the anon is m,so y=mx
By using the information find the value of m.
12=2m,m=6
So substite,6 and 7 to the equation.
Y=6(7) then you will get 42

Answer 2

Function of equation is x * 6 = y

Using this, 7 x 6 = 42.

Your answer is c, or 42.
