Jason and Mary will usually both run 4 miles each time they go running. This month, Jason ran an additional 15 miles. Which answer choice shows an expression that represents the total distance Jason and Mary ran this month if J = the number of times that Jason ran and m = the number of times that Mary ran? Answer Choices: 4j+4m+15, 8j + 8m + 15, 19j + 19m, 4j +19. Please answer if you know

4j+4m+15

Step-by-step explanation:

jason+mary= 4 miles which= 4j+4m

jason ran additional 15 miles= +15

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
