Sarah makes smoothies by blending apple juice and orange juice. The table shows the amounts of apple juice and orange juice that Sarah uses to make smoothies. 1. Use Row 1 to write a ratio for the amount of apple juice and used 1 smoothie

2. Use Row 3 to write an equivalent ratio for the amount of apple juice to orange juice used in 3 smoothies. To creat this ratio, what did Sarah do to each number in row 1?

Can someone please please help me with this answer.

answer: y = -2.5x - 15

              (-6,0)

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!
