1. a. 5 < 8> 4 since 6 is to the right of 4 on the number line. c. 16 < 82> 3 is true. 7. a. |8| = 8 since 8 is 8 units from 0 on a number line. b. |9| = 9 since 9 is 9 units from 0 on a number line. c. |2.5| = 2.5 since 2.5 is 2.5 units from 0 on a number line. b. 3  8 is false, since neither 3 > 8 nor 3 = 8 is true. d. 5  5 11 11 since 5 11 is 5 11 unit from 0 on a c. 25  25 is true, since 25 = 25 is true. number line. d. 4  14 is true, since 4 < 14 xss=removed xss=removed> 0 since 3 > 0. c. |7| < |11| since 7 < 11> |2| since 3 > 2. e. |0| < |4| since 0 < 4> are called inequality symbols. 4. The integers are {..., 3, 2, 1, 0, 1, 2, 3, ...}. 5. The real numbers are {all numbers that 3 4 5, 3.7, 8.8, 99. correspond to points on a number line}. 6. The rational numbers are 6. a. 0 < 3>
