Two trains leave the station at the same time, one heading east and the other west. the eastbound train travels at 85 miles per hour. the westbound train travels at 75 miles per hour. how long will it take for the two trains to be 224 miles apart? do not do any rounding. __hours

maybe - definition of supplementary angles. im not sure. sorry

step-by-step explanation:

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.
