Triangle ABC: A(-1,-1), B(-1,3) C(-4, 3) is transformed to triangle A'B'C: A (4.0) B(1.4) C'(4.4). Describe the transformation. Are these triangles congruent? Explain how you know they are or are not congruent

Given the system of equations presented here: 2x + 4y = 14 4x + y = 20 which of the following actions creates an equivalent system such that, when combined with the other equation, one of the variables is eliminated? multiply the second equation by â’4 to get â’16x â’ 4y = â’80 multiply the second equation by â’1 to get â’4x â’ y = â’20 multiply the first equation by 2 to get 4x + 8y = 28 multiply the first equation by â’1 to get â’2x â’ 4y = â’14
