Adam wanted to play his video games. His mother told him that he needed to finish his homework, clean out the dishwasher, and clean his room before playing video games. He completed his homework in 48 minutes. He took 25 minutes to clean out the dishwasher. He took 75 minutes to clean his room. How much time did Adam have to spend doing homework and cleaning before playing video games?

10

step-by-step explanation:

7+3=10

the direct variation says that:

then the equation is of the form is given by:

            where k is the constant variation.

from the given table:

consider any value of x and m(x)=y

x = 2 and m(x)=y = 3

substitute these value in [1]; we have;

divide both sides by 2 we get;

⇒

check:

put x = -1 and m(x) = -1.5

substitute in the equation:

-1.5 = -1.5                   true

therefore, the function m(x) represents a direct variation
