Agroup of 29 friends gets together to play a sport. first, people must be divided into teams .each team has to have exactly 4 players, and no one can be on mor than one team. how many teams can they make? (it is possible that not everyone can be on a team.)

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?
