Announcements

Note that 6.7 will not be covered on the final, nor will section 7.1 or 7.2(any polynomial equations on the final to be solved will factor more or less easily). Pay particular attention to 6.8, as that is sure to show up. Make sure you remember how to solve inequalities such as "2x-1>3" and "|x+2|<4" and state the solutions in interval notation. Other notable topics that are sure to show up are functions and their domains, systems of linear equations, and systems of inequalities. Of course, any material from the first test or any of the quizzes is fair game.

Here are the solutions for the first test : Page 1 Page 2 Page 3 Page 4


Here is the correct graph for # 2 from quiz 2. The lines have equations y = (1/3)x -2 and y = (1/4)x - 3.

Bonus Problem(due 2/7 for +1 quiz point): Susan's Explorer holds 7.4 L of coolant mixture. Her mechanic mixes her coolant with 70% water and 30% antifreeze. She is furious because it is May and she knows that you need less water for it to flow in warm weather. As such, she wants a 50/50 mixture. Rather than draining all of the coolant and starting over(he doesn't want to waste it because it can't be reused, and Susan is not very patient...), he wants to drain the right amount and refill it with pure antifreeze to obtain the right mixture. How much does he need to drain and refill with pure antifreeze?
