The coordinates of the vertices of quadrilateralABCD are-A(-3,4), B(-1,3), C(-3,-1), and D(-4,2). Jorge- states that quadrilateral. ABCD is a parallelogram. Prove or disprove-Jorge's statement

Two lines that do not intersect are skew. always sometimes or never

When using the linear combination metho e linear combination method to solve a system of linear equations, the four options are:

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
