**Unformatted text preview: **Review for Test 2 Friday, March 11, 2011 Sections 3.1-3.3, 4.1-4.3, 4.5 Create systems of equations to model linear functions and use model to compare the functions (find solution to the system) (Q2), review. P. 205-#4 Solve systems of equations by elimination or substitution. (3A1, 3A2, 3A6, 3A7, 3A9, 3A10), review. P. 205- #11a Determine how many solutions a system of equations has and describe the graph of the system. (3A3, 3A8) Work with linear inequalities and systems of linear inequalities (Q1), review. P. 205-#5,6 Convert numbers to and from scientific notation (4A1, 4A2, 4A4)-review p. 259-#21a Solve simple absolute value equations (Q3) Simplify expressions with exponents that are positive, negative, 0, or fractions. (4A5, 4A6, 4A7, 4A8, 4A9)- review p. 257-1,2 Simplify expressions with radicals. (4B19, 4B11, 4B14, 4C8, 4C9, 4C10) Remember the text website with chapter quizzes you can use to review. We did not cover section 3.4 (on piecewise defined functions) and section 4.4 (on metric units), nor 4.6-4.7 (order of magnitude and logarithms). piecewise defined functions) and section 4....
