19. Kaci spent $170 on 82 gold and silver tickets for the fair. Gold tickets, g, cost $2.50 each; silver tickets, s, cost $1.50 each. The system of equations below can be used to
determine the number of each type of ticket Kaci bought.
g+s= 82
2.5g + 1.5s = 170
How many gold tickets did Kaci buy?

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.
