Lily has $500 in the bank when the year begins. Each out the same amount of money. After 8 weeks she has $436 left in the
bank. Which equation can be used to model this scenario where W is the
number of weeks that has passed since the beginning of the year and M.
is the amount of money remaining in the bank?
(3) M= -8W + 500
(4) M=8W - 500
(1) W = -8M + 500
(2) W = 8M - 500

factor trees are nice.

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.
