Acircle is centered at (5, −9) and has a radius of 12. which of the following is the equation for this circle?
a: (x − 5)2 + (y + 9)2 = 12

b: (x − 5)2 + (y + 9)2 = 144

c: (x + 5)2 + (y − 9)2 = 144

d: (x + 5)2 + (y − 9)2 = 12

Me solve this problem, and someone clearly explain to me how to solve it.1.) use the value of the discriminant to determine if the given trinomials has 2 real solutions, 1 real solution, or no real solutions.a.  x2  − 4x  − 7 = 0b. 4r2  + 11r  − 3 = 0c. 3m2  + 7 = 0d.  t2  + 2t  + 1 = 0

1.based of the diagrams what is the the value of x? 2.how would you verify your answer for x
