Which statement is true about the number of vertices of any pyramid? a. it is equal to the number of edges. b. it is equal to the number of faces. c. it is twice the number of vertices of its base. d. it is the number of vertices of its base plus 2.

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

graph of this function as shown below:

the answer is simply just 6n add the two together as they have an n
