Mark and Josiah started skating at the same time in the same direction, but Josiah had a head start 12 meters past the starting line. Mark skated 2 meters per second and Josiah skated 4 meter per second. Write an equation that models the distance, d, Josiah skates as a function of time, t. d(t)= Write an equation the models the distance, d, Mark skates as a function of time, t. d(t)= At what time have the two skated the same distance? When t = seconds​

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?
