The vertices of triangle ABC are A(1,1), B(1,5), and C(7,1). If triangle ABC is reflected across the x-axis to create triangle A'B'C', what would be the new coordinates for the vertices of this new triangle?

The mean of a set of data is -3.82 and its standard deviation is 2.31. find the z score for a value of 3.99.

2x minus y equals 6, x plus y equals negative 3
