Solve each problem. Show your work. If your work does not get you the correct answer copy the correct solution when we go over the
problem in class. If there is no “work” to show, write a sentence to explain how you got your answer. This paper will be collected at the
end of the week. If you are absent, it is your responsibility to get the missing part and try, or to get the notes from a classmate.
Choose the proper description for each equation. Explain your reasoning.
