Dev. Algebra II-Chapter 1 Review Name:______________________________ TIPS: Study by DOING practice problems not just reading over your notes, quizzes, etc. Remember…NO WORK = NO CREDIT on tests! Give an example of each term from your notes or textbook: Associative Property___________________________________________________________ Commutative Property__________________________________________________________ Distributive Property___________________________________________________________ Power_______________________________________________________________________ Reciprocal____________________________________________________________________ Evaluate: HINT: Plug in value for x and solve 2 8x2 2 x when x 6 Evaluate: HINT: Simplify the problem by using the correct order of operations (PEMDAS) 7 3(4) 6 (1 2) (12 3) Solve for y. HINT: Get y by itself 5 y 15 x 20 Solve for x. HINT: Get rid of the fractions by multiplying every term by the LCD (Least Common Denominator) 2 3 2 x 3 5 15 Solve for x. HINT: Distribute first, combine like terms, get x’s on one side and integers on the other to find the value of x. 5( x 3) 12 2( x 2) Solve the inequality. HINT: Get x by itself…what you do to the middle term, you must do to the first and last terms too. If you multiply or divide by a negative, you must flip the inequality signs. 2 1 3x 10 Solve and graph the inequalities. HINT: Solve each inequality separately the same as you would an equation. Plot the points separately on a number line (remember…< and > are open dots and and are solid dots) and shade. or 2x 5 1 x 1 0 Solve the absolute value. HINT: Absolute values have two solutions so two separate equations are needed. Solve each separately. 4 3x 16 Solve and graph the inequality. HINT: Look at the inequality sign to determine method to solve. > and are set up using two separate equations. Plot the points separately on a number line and shade in opposite directions. 2x 7 1 Solve and graph the inequality. HINT: Look at the inequality sign to determine method to solve. < and are set up using one large equation. Plot the points on a number line and shade between the points. 4x 7 9 BONUS- HINT: study 1.4 day 2 notes
