Jackie runs and dances for a total of 55 minutes every day. she dances 25 minutes more than she runs. part a: write a pair of linear equations to show the relationship between the number of minutes jackie runs (x) and the number of minutes she dances (y) every day. (5 points) part b: how much time does jackie spend running every day? (3 points) part c: is it possible for jackie to have spent 45 minutes dancing every day? explain your reasoning. (2 points)

the answer is (-8,-5)

step-by-step explanation:

the endpoint to midpoint is half the length. the length is (-2,-1) so when you are at the midpoint just add it to it to find your answer -6+(-2)= -8 and -4+(-1)=-5 so (-8,-5)

1. perpendicular

2. parallel

3. perpendicular

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!
