Write a two- column proof.

Given: 3x = x + 12
Prove: x =5

Abcd ≅ klmn ≅ pqrs ≅ wxyz given that information, which figures are reflections of abcd?

The border line of the linear inequality 4x + 7y < 5 is dotted true or false?

What are the solutions of the system? y = x^2 + 2x +3y = 4x - 2a. (-1, -6) and (-3, -14)b. (-1, 10) and (3, -6)c. no solutiond. (-1, -6) and (3, 10)
