Anthony has a cup full of nickels and dimes worth $6.80. There are 82 coins all together.
Which of the following systems of equations correctly models this situation?
x+y= 680
5x+10y = 82
B. 5x+10y = 680
x+y=82
5x +y = 680
x+10y = 82
D. 5x+y=82
x+10y = 680

im with everythinglos so yeahhhhh

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!
