Which diagram can be used to prove △ABC ~ △DEC using similarity transformations? Triangle A B C is rotated about point C and then is dilated to form smaller triangle C E D. Triangle A B C is reflected across side A C and then is dilated to form smaller triangle C E D. Triangles A B C and C E D have different angle measures. Right triangle A B C is shown. Line segment D E is drawn near point C to form triangle D E C.

Which statement best explains whether the table represents a linear or nonlinear function? input (x) output (y) 2 5 4 10 6 15 8 20 it is a linear function because the input values are increasing. it is a nonlinear function because the output values are increasing. it is a linear function because there is a constant rate of change in both the input and output. it is a nonlinear function because there is a constant rate of change in both the input and output.
