Traditional college algebra final exam spring 2015. Directions: you will nd 20 problems listed below. The point value of each problem is given in paren- theses. Please show all your work neatly and box your nal answers. Graphing calculator models above the level of a ti-84 plus are not allowed (in particular, calculators with a built-in cas and/or qwerty keyboard are not allowed). Leave exact (don"t use a calculator): (8 points) solve: |3x 8| < 11, (10 points) graph 3x + 2y = 8 and 4x + 3y = 6 on the grid below. Label all intercepts clearly as ordered pairs (be sure to nd x and y intercepts on both lines). Are the two lines parallel, perpendicular, or neither: (5 points) solve the quadratic equation 3x2 + x 5 = 0, (7 points) the pro t function for selling x units of a certain product is given by. P (x) = x2 + 1000x + 380, 000.
