 Algebra 1, 5th Edition(new program since July 2009)Corrections and Clarifications The Section Exercises are at the end of each section. The student will usually have 75 to 120 odd problems per Section from which to choose, but the good news is that only 25-30 problems per section need to be worked. And this will be about every 3rd or 4th odd problem. Student Solutions Manual. The Chapter 1, Section 1 odd problems start on page 2. The Mid-Chapter Quiz and End-of-Chapter test for each chapter are fully supported for both even and odd problems and every problem should be worked. Chapter 2 Test, problem 5. The answer in the solutions guide should be Additive Identity Property. Section 4.2, problem 9. In the solutions guide, the table of values is incorrect but the graph is accurate. The y-values in the table should be 11, 10, 9, 8, 7. Section 4.2, problem 13. In the solutions guide, the table of values is incorrect but the graph is accurate. The y-values in the table should be 7, 4, 3, 4, 7. Chapter 6 Test, problem 9. In the solutions guide, the leading coefficient 9 should not be included in the problem. Chapter 7, Mid-Chapter Quiz, problem 20. The area of a rectangle is calculated using the formula, Area = (length)(width). The area of the shaded rectangle is Area = (x + 3)(x) The total area of the figure is Area = (x + 10)(x + 3) The ratio of the area of the shaded region to the total area of the figure is a fraction with the area of the shaded region in the numerator and the total area of the figure in the denominator. Once the fraction is formed, the factors of the (x + 3) cancel leaving the fraction x / (x + 10). Algebra 1, 2nd edition from Oct 2000Corrections and Clarifications At the end of each section, problems under Integrated Review may be omitted. Problems under Solving Problems may be limited to about 5 to 6 problems. Problems under Explaining Concepts may be omitted. How to correlate your solutions guide to the textbook. Solutions to Integrated Review Exercises for Chapters 2-10; Pages 1-54, Index on page 1. Solutions to Odd-Numbered Exercises for Chapters 1-10; Pages 55-497, Index on pages 55-57. NOTE: Goldenrod divider page in middle of book Solutions to Even-Numbered Exercises for Chapters 1-10; Pages 2-371, Index on pages v-vii. Example of Chapter 1 Text correlation to Solutions Guide: Odd exercises on pages 55-57 Even exercises on pages 1-16 (after goldenrod divider) Chapter Test page 79 is missing. If you have a question about a specific problem contact Dana Mosely. Click here for more information on Solution Guides. Chapter 1 Test. Pages 79 and 80 are missing from the Algebra 1 Complete Solutions Guide, and these pages would have covered the end-of-chapter test for Chapter 1, Algebra 1 textbook. Answers to the Chapter 1 Test are in the back of the Algebra 1 textbook on page A39, and step by step solutions are below. Algebra 1 Chapter Test for Chapter1 (a) 8 and 12/4The fraction 12/4 is natural because is reduces to 3. (b) -10, 8, and 12/4 (c) all of the numbers are rational because they can all be written in the form a/b. -3/5 _____ -| -2 | -3/5 ______ -2 Since -3/5 lies to the right of -2 on the number line, -3/5 is greater than -2, so -3/5 > -2 16 + (-20) 16 - 20 -4 -50 - (-60) -50 + 60 10 7 + | -3 | 7 + 3 10 64 - (25 - 8) 64 - (17) 64 -17 47 -5(32) -160 -72 / -9 8 (12 + 9) /7 21 / 7 3 - (-2) (5) / 10 - (-10) / 10 10 / 10 1 5/6 - 1/8 20/24 - 3/24 17/24 -27 (5/6) -9 (5/2) -45/2 7/16 ö 21/28 7/16 x 28/21 1/4 x 7/3 7/12 -8.1/0.3 -27 -(2/3)2 Notice the base of the exponent is 2/3, so there are two factors of 2/3 -(2/3) (2/3) - 4/9 35 - (50 ö 52) 35 - (50 ö 25) 35 - 2 33 The Distributive Property The Multiplicative Inverse Property The Associative Property of Addition (because the grouping of numbers changed) The Commutative Property or Multiplication (because the order of the factors changed) 30/72 working in easy steps, divide 3 into both numerator and denominator to get 10 /24, now divide 2 into both numerator and denominator, 5/12 In the first expression the base of the exponent is 3 but in the second expression the base of the exponent is -3. Exponentiation (raise 2 to the 3rd power), multiply (3 times 8), subtract (24 from 32) Answers vary. Among them are 2/3, 4/6, 6/9, 8/12. Chapter 1 Review, problem 11. In the solutions guide the answer should be -8.5 rather than 8.5. Chapter 1 Review, problem 67. Please also accept as correct the expression n + 10/8 which is technically more correct than a fraction with n + 10 as the numerator and 8 as the denominator. If it were intended for the numerator to be n + 10, then the punctuation in the sentence would be: The sum of a number and 10, divided by 8. Section 1.2, problem 124. In the solutions guide, the prime factorization should contain 3 factors of 3. Section 1.3, page 43, problem 153. The answers for parts "h" and "i" are switched; "h" should be 15 degrees and "i" should be 14 degrees. Chapter 2 Review, #94. In the solutions guide, the minus sign should be a times sign. Chapter 2 Review, #99. In the verbal model, the first item should be "Area of rectangle" rather than "Area of triangle." Section 3.1, #69. In the solutions guide, the division signs should be equal signs. Also, in the 4th step, 4 should be subtracted from both sides rather than added to both sides. Section 3.1, #71. In the solutions guide, the division signs should be equal signs. Section 3.2, Integrated Review, problem 7. The answer in the textbook (page A44) is incorrect. The correct answer is x - 4. Section 3.5, problem 9. The solution requires the use of a technique called factoring which is covered in a later chapter. Please omit the problem. Section 3.5, problem 65. In the solutions guide, second step, the first term should contain a factor of x. Section 4.2, problems 79 and 81. In the Solutions Guide, the Xmin values should be negative rather than positive. Section 4.3, Integrated Review, problem 6. The middle term of the answer in the Solutions Guide is incorrect. The answer should be 3x^2y - xy^2 - 5xy. Section 4.4, problem 26. The answer in the solutions guide is correct but, in the second to last step, the denominator fraction should be 17/8 rather than 17/18. Section 6.5, problem 11. The second answer in the solutions guide should be -100/7 rather than 100/7. Section 6.5, problem 95 (c). In the solutions guide when the monomial factor of -4 is taken out of the trinomial, the middle term should be -20x rather than 20x. Section 6.5, problem 99 (b). The answer is incorrect in the solutions guide -- t should be 13 rather than 15 and the year should be 2003 rather than 2005. The window settings must be extended up and to the right in order to view and trace to the positive where y=100 (for 100 million passengers). The corresponding x-value (which stands for time) is approximately 13 rather than 15 listed in the solutions guide so the year is 13 years beyond the basis year of 1990, or the year 2003, rather than 2005 listed in the solutions guide. Section 7.4, problem 51.In the solutions guide, page 306, the product R=8950(96) should be 859,200 rather than 859,000. Section 7.4, Integrated Review, problem 2. The answer in the solutions guide is not related to the problem in the textbook. The correct answer should be: The domain of the function is 2
