Write the coordinates of the vertices after a reflection across the line y = - 3 E ( -8,3) F (-6,3) G (-9 , -3 )

Find the value of x for which the lines are parallel.

Select the margin of error that corresponds to the sample mean that corresponds to each population: a population mean of 25, a standard deviation of 2.5, and margin of error of 5%

If cos(2x) = tan^2(y), show that cos(2y) = tan^2(x).
