Ellie said, "you can regroup the 440 minutes Krystal spent on each activity as hours." What does Ellie mean? How many hours did Krystal spend on each activity?

Krystal spent 7.33333 hours

Step-by-step explanation:

Ellie means that the amount spent can be represented in hours rather than minutes

1 hour = 60 minutes

X hour = 440 Minutes

X = 7 hours 20 minutes

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
