Solve the equation. then check your solution. 11-19m=-16m-16

11-19m=-16m-16

move -16m to the other side

sign changes from -16m to +16m

11-19m+16m =-16m+16m-16 ( combine like terms)

11-19m+16m=-16

11-3m=-16

move 11 to the other side

sign changes from +11 to -11

11-11-3m=-16-11

-3m=-16-11

-3m=-27

divide both sides by -3 to get +m and by itself

-3m/-3=-27/-3

m=9

Check solution by using substitution method

11-19m=-16m-16

11-19(9)=-16(9)-16

11-171=-144-16

-160=-160

m=9

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.
