Afamily wants to rent a car to go on vacation. company a charges $30.5030.50 and 10 cents per mile10¢ per mile. company b charges $55.5055.50 and 17 cents per mile17¢ per mile. how much more does company upper bcompany b charge for x miles than company upper acompany a?

if a = 1,   and b = 2, then the answer is 47.99999999. if you round that to the nearest whole number, the answer is 48.

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.
