Peter charges a flat fee of $3.75 for each delivery plus $0.10 per mile for each mile he drives. Maria charges a flat fee of $2.25 for each delivery plus $0.25 per mile for each mile she drives.

191 students play sports and ninety-seven 10th graders were surveyed.

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!

time is equal to distance over rate so

t = d/r

need a little bit more information for the second question.
