TEST BANK FOR Elementary Linear Algebra with Applications 9th Edition By Kolman, Hill

Linear Equations and Matrices Section 1.1, p. 8 2. x = 1, y = 2, z = −2. 4. No solution. 6. x = 13 + 10t, y = −8 − 8t, t any real number. 8. Inconsistent; no solution. 10. x = 2, y = −1. 12. No solution. 14. x = −1, y = 2, z = −2. 16. (a) For example: s = 0, t = 0 is one answer. (b) For example: s = 3, t = 4 is one answer. (c) s = t2 . 18. Yes. The trivial solution is always a solution to a homogeneous system. 20. x = 1, y = 1, z = 4. 22. r = −3. 24. If x1 = s1, x2 ...
