Garrett drove 432 Miles on 18 gallons of gas Derrick drove 364 miles on 14 gallons of gas who had the better gas mileage?

Derrick

Step-by-step explanation:

Garrett: 432 divided by 18 = 24

Derrick: 364 divided by 14 = 26

c. 4 1/4 pounds

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
