Tools - Question 14
Determine whether each ordered pair is part of the solution set of the system of inequalities.
Select the THREE ordered pairs that are in the solution set.
3x + 2y = 6
4x - y = 8
Hint: Graph the system on your graph paper to help you determine the ordered pairs
that are solutions.
A
(0,4)
В
(4,0)
С
D
(4.0)

the correct option is:

b. a value of the variable that makes the polynomial equal to zero.

the root or roots of a polynomial are the values of the variable that makes the polynomial equal to 0. we can find the roots of a polynomial making the expression equal to 0 and then, isolating the variable (it it has just one variable).

for example, given the following polynomial:

the root or zero of the polynomial, can be found by making the expression equal to 0, and then, isolating the variable, so, finding the root we have:

therefore, we have that the root of the polynomial is equal to 2.

we must remember that the number of roots that a polynomial can have, will depend on the degree of the polynomial, a first degree polynomial have will have one single root, a second degree polynomial (quadratic expression) may have two roots and so.

hence the correct option is:

b. a value of the variable that makes the polynomial equal to zero.

have a nice day!
