4- Fernando has two equally-sized containers of clay which he is using to build a pyramid-like structure. The finished structure will consist of four
square-based, two-inch thick slabs of clay, with each slab two inches less
wide than the one beneath it.
Fernando has one-half of a container of clay left after forming the first
two slabs. Does he have enough clay to finish the structure?

answer: a. 74

step-by-step explanation:

it shows divided evenly, so add the 37+37 = 74

the mean and mad

step-by-step explanation:

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
