Without graphing, classify each system of equations as independent, dependent, or inconsistent. Solve independent systems by graphing. 1) 5 - y = 2x 6x - 15 = - 3y 2) 6y + 2x = 8 12y + 4x = 4

Which of the following expressions is the inverse of the function y = 3x + 4? a) y = 3x - 4 b) y = - 3x - 4 c) y equals quantity x minus 4 divided by 3 d) y equals quantity x plus 4 divided by 3

Simplify: - 0.8b + 4.1c - (-3.2b) - 0.1c A) - 2.4b + 4c B) 2.4b + 4c C) 2.4c + 4b D) 2.4b - 4c
