Rotation, Translation, and Reflection are the 3 rigid motions that preserve angle measure and side length. A dilation only preserves angle measure. Therefore, the answers are A, C, and D
The system of equations:2 y = - x - 12 y = x + 5---------------------- x - 1 = x + 5- 2 x = 5 + 1- 2 x = 6x = - 6 : 2x = - 32 y = - 3 + 52 y = 2y = 1The solution is ( - 3 , 1 ).Answer: The x-coordinate of the solution to the system is: x = - 3.
