Question

4. Suppose y varies directly with x, and y = 24 when x = 8. What is the value of y when x = 10?
A. 10
B. 30
C. 80
D. 240

Answer 1

y = kx

Plug in y = 24 and x = 8. Solve for k.

24 = 8k

k = ?

Answer 2

Hint:

Divide 8 on both sodes

Answer 3

Ohhh yeah I was confused on that how did you know that lool

Answer 4

y = kx is the equation for direct variation, where k is the constant of proprtionality.

Answer 5

proportionality*

Answer 6

Wait 24 divided by 8 is 3

Answer 7

So, k = 3

the equation is y = 3x

Now, we plug in x = 10

y = 3 (10)

y = ?
