Solve for the value of m.

M= 17.25

Step-by-step explanation:

8m+4+38=180

8m+42=180

8m+42-42=180-42

8m=138

8/8=138/8

m=17.25

Check:

17.25*8+4+38 = 180

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
