Weston used the steps below to determine the percent equivalent to 1/40

What is the range of the relation in the table below? x y –2 0 –1 2 0 4 1 2 2 0

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

The distributive property allows you to say that 3(x − 1) = 3x −
