TOOLS Use the unit fraction 1/9 to represent the space between the tick marks on the number line. Write an expression involving subtraction that is being modeled. Then find the difference.

A number line with two arrows on top of it. It has two tick marks to the left of 0 and four tick marks to the right of 0. One arrow begins at 0 and ends at the third tick mark to the right of 0. Another arrow begins at the third tick mark to the right of 0 and ends at the second tick mark to the right of 0.

An expression is ___

The difference is ___

$649.60

step-by-step explanation:

answer: b

step-by-step explanation:

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!
