Let y be the cost of 1 year of college at Benjamin Franklin Institute of Technology and x be the number years after 2000. The equation for the rising cost of college tuition at
Benjamin Franklin Institute of Technology is:
y = 1,057x + 18,190
How much will it cost in
2030 (30 years after 2000):
2040 (40 years after 2000):
2070 (70 years after 2000):

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.
