MATH 0930 Beginning Algebra Part 1 K.Rigdon Name_________________________ Practice Test for Exam 2 – Sections 1.8-1.10 Due (optional) on Test Day –Thursday, 9/25/2014 This practice test will give you a good idea of the type and number of problems you will see on the actual test. Working through this practice test will, therefore, provide you with a good idea of how well you know the material you will be tested over. You have the opportunity to earn up to 3 extra credit points toward your test grade if you show all work possible for all the problems and, of course, get all the answers correct (answers are included for you to check your work). If you would like to earn these extra points, you will need to turn in this packet, with your work attached (done on separate lined paper), on the day of the Exam. Good to try to have it done by the Review Day, Wed., 9/24/14 In addition to the questions over the current material, you will have 3 questions like the Cumulative Review Questions you have been having in your homework assignments or on Cumulative Review Worksheets, so be certain to go over them (but, you don’t have to rework them to turn in with this). Specifically, these homework problems were: Problems 1), 2), & 3): Page 70; #146-150 all 4. 6. 8. 10. 12. 14. 16. 18. 20. 22. -3(6) 5(-8) (7)(-2)(-3) 24.
