I need to know who is candice

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

Which is f(5) for the function –2x2 + 2x - 3?

What is the slope of the line that contains the points (-5, 6) and (14. - 7)?
