A. x = 3, y = t, z = -1; r = (3, 0, -1) + t(0, 1, 0) B. x = 3, y = t, z = -1; r = (0, 1, 0) + t(3, 0, -1) C. x = 3t, y = 1, z = -t; r = (0, 1, 0) + t(3, 0, -1) D. x = 3t, y = 1, z = -t; r = (3, 0, -1) + t(0, 1, 0)
Use the following definitions to translate the statement into words. p: The monitor is included. q: The color printer is optional. r: The zip drive is extra.~(p ? q) ? (r ? ~q)
A. If the monitor is included and the color printer is optional, then the zip drive is extra or the color printer is not optional. B. It is not true that if the monitor is included or the color printer is optional, then the zip drive is extra and the color printer is not optional. C. It is not true that if the monitor is included and the color printer is optional, then the zip drive is extra or the color printer is not optional. D. If the monitor is included and the color printer is optional, then it is not true that the zip drive is extra or the color printer is not optional.
