A theater charges $8 for main floor seats and $5 for balcony seats. If all seats are sold, the ticket income is $4200. At one show, 25% of the main floor seats and 40% of the balcony seats were sold and ticket income was $1200. How many seats are on the main floor and how many are in the balcony

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!

but there’s no any figure there!

step-by-step explanation:

a'(12.5,11.25)

slope=(y1-y2)/(x1-x2)
