Jake is comparing the prices of two laundry service companies. company a charges $20 per load and an additional $8 as service charges. company b charges $24 per load and an additional $4 as service charges. part a: write equations to represent company a's and company b's total laundry charges for a certain number of loads. define the variable used in the equations. (4 points) part b: which company would charge less for 5 loads of laundry? justify your answer. (3 points) part c: how much money is saved by using the services of company a instead of company b to clean 9 loads of laundry? (3 points)

just keep asking questions until you have a better understanding.

step-by-step explanation:

y=sec x is the correct answer

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.
