15) Scott is hiking in Grizzly Park. In the morning he hiked 4.5 miles. In the afternoon he hiked at a rate of 2.5 miles per hour. Which equation can be used to find y, the total distance he hiked if he hiked for x hours in the afternoon? (7.7A, RS,

RC2)

A) y = 4.5x + 2.5

C) y = 4.5x - 2.5

B) y = 2.5x + 4.5

D) y = 2.5x 4.5

Is it A, C,B, or D?

the answer is d on edge

step-by-step explanation:

answer:

a=9

step-by-step explanation: lmk if you need a 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!
