A pair of equation is shown below y = 7X - 8 and y = 5x - 2 part A explain how you will solve the pair of equations by substitution or elimination show all the steps and write the solution part B if the two equations are graphed at what point where the lines representing the two equations intersect explain your answer

You drop a rubber ball off the roof of a 50 meter high building onto a paved parking lot. it bounces back up with every bounce, but not quite all the way back up to you. after the first bounce it bounces back only 80 percent of the distance it was dropped from. the pattern continues, meaning after every bounce it comes up to just 80 percent of the previous maximum height. so if before the first bounce the height is 50 meters, what height does the ball reach after the fifth bounce? round your answer to one decimal place and chose the correct response from the choices below:

Graph the equation. select integers for x
