Math 71 Intermediate Algebra

• If you are considering taking a lower-level class than Math 71:
• We encourage you to consider taking the corequisite course—Math 7—which provides additional support for Math 71.
• You might consider taking the two-semester Math 71A/71B sequence, which covers the same material as Math 71, but at a slower pace.
• The next level lower is Math 51 (Elementary Algebra).

• Sample of what you should know before taking Math 71:
1. Solve • Solution     2. Solve • Solution     ; but does not work, thus 3. Graph the solutions set • Solution 4. Simplify • Solution  5. How many mL of a 15% acid solution and how many mL of a 3% acid solution must be mixed to get 45 mL of a 7% acid solution?
• Solution
Let x = amount of 15% acid solution and y = amount of 3% acid solution.    15 mL of 15% acid solution and 30 mL of 3% acid solution

• Sample of what you will learn in Math 71:
1. Graph • Solution 2. Solve and write your answer in exact form • Solution     3. Solve and write your answer using interval notation • Solution or  or  or  4. Solve • Solution
Let equation becomes
