jackie runs and dances for a total of 55 minutes every day. she dances for 25 minutes longer than she runs.

part a: write a pair of linear equations to show the relationship between the number of Jackie runs (x) and the number of minutes she dances (y) every day.

part b: how much time does jackie spend running every day? show your work

part c: is it possible for jackie to have spent 45 mins dancing if she runs and dances for a total of exactly 55 minutes and dances for 25 minutes longer than she runs? explain your answer

i believe the answer is d.

hope it you! : d

step-by-step explanation:

options

center (1,3) with radius 6

step-by-step explanation:

we must complete the square to find the center and radius of the circle.

first make sure the x and y squared terms have 1 as their coefficients. we also make sure x and y terms together.

we now create space between the x and y terms with parenthesis.

we complete the square by taking the middle terms -2x and the -6y - divide each and square them.

we add the squares to both sides.

simplify.

and write the quadratics in factored form.

the center is (h,k) or (1,3). the radius is the square root of 36 which is 6.
