You've determined that, in a direct variation problem, the constant of variation (k) is 1/8. what is the value of y when x is 12? just type the value of y (a number). if it's an integer, type the integer. otherwise, write it as a fraction in simplest form.

ANSWER

When the value of x is 12, then,

EXPLANATION

The statement, y varies directly as x is written nathematically as

If we introduce the constant of proportionality, then we can write the equation,

where k is the constant of proportionality. It is also called the constant of variation.

If

, then the direct variation equation becomes.

When

, then

This simplifies to

d. is the correct answer

step-by-step explanation:

if x decreases by 4 then y increases by 10
