Concepts of Intermediate Algebra: An Early Functions ApproachBrooks/Cole Publishing Company, 1996 - 706 páginas This comprehensive book from Dave Gustafson is perfect for a one-semester course where early coverage of graphing and functions is used to explore the mathematics and applications. All the topics generally found in a one-semester intermediate algebra course are here, but with a modern twist: Gustafson emphasizes conceptual understanding, early treatment of graphing, problem solving, and use of technology (graphing calculators). |

... Divide both sides by 7. Step 4: To find x, we substitute -3 for y in either of the original equations and solve for x. If we use Equation 5, we have 4x + y = 13 4x + (–3) = 13 Substitute -3 for y. 4x = 16 Add 3 to both sides. x = 4 Divide ...

An Early Functions Approach R. David Gustafson. For example, if both sides of the true inequality –4 - 6 are multiplied by +2, we get 2(−4) < 2/6) –8 × 12 and the 3 symbol is unchanged. Dividing both sides by +2 does not change the ...

... both sides. x < 6 Divide both sides by 6. The solution set is the interval (-oo, 6), whose graph is shown in Figure 4-1. The parenthesis at 6 indicates that 6 is not included in the solution set. Solve the linear inequality -4(3x + 2) ...
