Dadas las ecuaciones generales, halla las coordenadas del centro de la circunferencia asi como el valor del radio A)x2 + y2 - 6x - 4y - 12 = 0 B) x2 + y2 - 10y - 11 =0 C) x2 + y2 - 2x + 2y - 7 = 0 D) x2 + y2 - 121 = 0

repeat the question

step-by-step explanation:

x= -3

step-by-step explanation:

step 1: simplify brackets

4 - x - 1 = 6

step 2: simpilfy

3 - x = 6

step 3: subtract 3 from both sides

-x = 6 - 3

step 4: simpilfy 6 - 3

-x = 3

step 5: multiply both sides by -1

x = -3

the correct answer is x/3+10≥32

hope this !
