1. what polynomial is represented by the factors (x-8)(x+5)? a. x^2-3x-40 b. x^2+3x-10 c. x^2+3x+40 or d. x^2-5x-8 2. find the gcf of the polynomial, 20ab^3+16a^2b+a. a. 4ab b. 4ab^2 c. b3 or d. a

1. A- foil to get correct answer

2. D- a is the only factor present in all numbers

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
