Larry Mitchell invested part of his 13000 advance at 6% annual simple interest and the rest at 5% annual simple interest. If his total yearly interest from both accounts was $750 find the amount invested at each rate.

Graph a triangle (xyz) and reflect it over the line y=x to create triangle x’y’z’. describe the transformation using words. draw a line segment from point x to the reflecting line, and then draw a line segment from point x’ to the reflecting line. what do you notice about the two line segments you drew? do you think you would see the same characteristics if you drew the line segment connecting y with the reflecting line and then y’ with the reflecting line? how do you know?
