a A local pizza shop has a membership program for frequent buyers. The membership costs $25 per month and members get a discounted price of $1.75 per slice of pizza. Isaac purchased a membership to this pizza shop. How much would Isaac have to pay the pizza shop if he bought 5 slices of pizza this month? What would be the monthly cost for x slices of pizza?

$33.75; 25+1.75x

Step-by-step explanation:

a) cost = membership fee + cost of pizzas

= 25 + 1.75*5

= 25 + 8.75

= ($) 33.75

b) cost = 25 + 1.75x

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.
