... Dave hits a ball along a path with height h = –16t2 + 15t + 3 where h is the height in feet and t is the time in seconds since the ball was hit. By chance, the ball hits a balloon released by a child in the crowd at the same time. The balloon’s height is given by h = 3t + 5. What height is the ballo ...

Joke of the Day Systems of Linear Equations in Two
... As shown in the previous examples, many systems of equations have one point or ordered pair that is the solution. However, there are other systems that have no solution or infinitely many solutions. For these special cases, while working the problem two things can happen: 1) You get a false statem ...
