Someone help me question below
(please NO LINKS)

Which equation represents a line that is parallel to the line whose equation is 3x-2y=7( show all work)

Simplify 15(x - 4)(x -1)-3(x + 4)(x - 1) with steps

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
