If solving a system of linear equations by elimination or substitution I get that 0=0, as final or intermediate step depending on the system, it means (check all that apply) I have definitely made a mistake and need to review the result

If the system of equations is 2 linear equations in 2 variables, there is infinity number
of solution

If the system of equations is 3 linear equations in 3 variables, there might be infinite
number of solutions

If the system of equations is n linear equations in n variables, there is one unique solution

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:
