I CANT ANYMORE I NEED HELP IMMA ABOUT TO HAVE A MENTAL BREAKDOWN JUST STARING AT THESE PROBLEMS

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

2/3(-6y+9x) expand each expression using the distributive property

Graph the system of equations. {6x−4y=−244x−8y=−32 use the line tool to graph the lines.
