Identify the Vertex, Range, and Domain

Which statement accurately explains whether a reflection over the x-axis and a 180° rotation would map figure acb onto itself?

The value of x in this system of equations is 1. 3x + y = 9 y = –4x + 10 substitute the value of y in the first equation: combine like terms: apply the subtraction property of equality: apply the division property of equality: 3x + (–4x + 10) = 9 –x + 10 = 9 –x = –1 x = 1 what is the value of y?

Will give a: 122 b: 90 c: 48 d: 180
