Math 17 TWHFW-7 1 st Sem AY 2011-12 Exercise Set 2 - Part 1 (HW 8) July 18, 2011 Use a separate piece of paper as your answer sheet. Show as complete a solution as you are able to. Remember to box all final answers. Submission is on Thursday, July 21. Good luck! YUKENDUEET! I. Find the solution set of the following equations: 1. 8 3 x 2 - 3 = 5 4( x - 1) - 3 2 x + 2 2. (2 x 2 - 3 x + 1) 2 + 2(2 x 2 - 3 x + 1) = 48 3. 2 x - 1 x 2 - 1 + x + 8 x 2 - x - 2 = 3 x - 1 x 2 - 3 x + 2 4. (2 x - 1)(2 x + 1) = 7 2 x 2 - x - 14 5. x + 33 = x + 3 6. 8 x + 5 - 6 x + 1 = 1 7. 2 2 x + 1 + 8 - x = 11 x + 20 8. radicalbig 2 2 x + 9 - 2 x = 1 9. | 2 x 2 - 4 x - 6 | = x - 3 10. | 4 x + 7 | = x + 2 11. | 5 x + 3 | = 2 x - 3 12. | x + 3 | = 2 - 3 x 13. | 2 x - 3 | - | 3 x + 2 | = 1 II. Solve for x in the following: 1. 2 x - 3( y + 2 x y ) = x - 1 y 2. pqx - 3 4 ( rx + p ) = pr ( x - q 2 p r ) 3. st 2 x 2 - abx + s = 0 4. Ax 2 + ( A + B ) x + B = 0 III. Perform the following as instructed: 1. Given the line L 1 with equation 2 x +4 y - 5 = 0, find the equations of the lines L || and L if L 1 ||L || , L 1 ⊥L and both L || and L pass through P ( - 1 , 3). Graph all three lines in one coordinate plane.
