Jacques will wash the windows of a house for $15.00 plus $1.00 per window. Ray will wash them for $5.00 plus $2.00 per window. Let x be the number of
windows and y be the total charge for washing them. Write an equation that
represents how much each person charges to wash windows. Solve the system of
equations and explain what the solution means and when it would be most
economical to use each window washer.

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:

What is the measure of ac? 5 units 13 units 26 units 39 units 3x- 2b 6x + 9
