Calulators may not be used on this exam. 1. Solve for x : 1 2 ( x- 1)- 1 3 x = 4 2. Solve for x : x 2 = 7 x- 5 2 . The sum of the two solutions is: a) 9 b)- 9 c) 5 d)- 5 e) None of the above 3. Solve for x : 2 x- 2 + 3 x- 1 = 2 4. A certain electrponic device is to be operated in an environment with relative humidity h in the interval defined by 4 h- 50 30 . Identify the minimum and maximum values of relative humidity possible for the operation of this device. Minimum: Maximum: 5.
