Apainter must add the areas of two walls to determine the amount of paint needed. the area of the
first wall is modeled by 4x2 + 12x + 9, and the area of the second wall is modeled
by 36x2 - 12 x + 1. write a polynomial that represents the total area of the two walls.

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

you probably already have the answer but anyways it's b. 15.0

step-by-step explanation:

question: how many people can she serve?

answer: she can serve 16.66666667 people. so she can only give 16 people a complete serving.

question: does she have enough ice cream for her guests?

answer: no. explanation: she only has enough for 16 people to have a full serving. however, she can give a 17th person a partial serving.

answer: i believe the answer is e
