What type of transformation has the same effect as each composition of transformations?
translation (x, y) > (x+4,y) followed by a reflection across the line y=-4
translation (x,> (x+4,y+8) followed by (x,> (x-2,y+9)
reflection across the line y=7, and then across the line y=3
reflection across the line y=x, and then across the line y=2x+5
these are all separate problems, not one.
