Using the net below, answer the following questions: a. if you were to fold up this net, what would the most specific geometric name of the object be? b. using the net, find the surface area of the total shape if the height of the triangles is 4 cm and the bottom edge is 2 cm. show your work and label your answer appropriately. (hint: you should not need a special surface area formula for this)

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
