Document Summary

Solutions to test 1: d. the point-slope form of the line is y 5 = 2(x 1). Converting the slope-intercept form: y = 2x + 3, giving a y intercept of 3: d. x2 9 = 4 = x2 9 = 42 = x2 = 25 = x = . 25 = x = 5: c. x2 2x 8 = 0. We can solve for x by factoring, completing the square, or the quadratic equation. In this spot we can factor the equation rather easily: x2 2x 8 = 0 = (x 4)(x + 2) = 0 = x = 2, 4: a. 3n is a geometric series with d = 2, r = 1. Since 1 < r < 1, this series converges to a value of. By the linearity of limits, this is simply 3 5 ( 2) = 17: c. the nal balance is 50 (1+ . 25.
