What is the value of x2?
(5x)
0 14
110
110
017
70

14

Step-by-step explanation:

110 + 110 + 70 + 5x= 360 ( total number of angles in a quadrilateral is 360 degrees)

290+5x= 360

5x= 360 - 290= 70

x= 70/5= 14

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
