3a.) If you are at -20 feet, how far would you need to go to get to 10 feet? (Think: what should you add to -20 to get to 10?)

-20+30=10        Add 30 ft

Step-by-step explanation:

If you subtract 20 from -20 you get 0 now if you add 10 you get 10 equal to the number you need to be equivalent to. 20+10=30 your answer is 30. You should add 30 to -20 to get 10.

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.
