Due: 21 September 2011 Math 1090-002 14 September 2011 Section 1.7 Homework Instructions: Complete the following problems in the space provided. Please show your work; write down enough so that a classmate could follow the steps you’ve taken to arrive at the solution. You can earn up to 30 points on the assignment. Note: I’ve changed some of the inequality signs from the way they are written in the textbook, so please be sure to do the problems the way they are written here. (The solution regions will still have the same shape.) Graph the solutions for the following inequalities (3 points each): 2. y< 1 x − 2. 3 1 11. 9 9 −2x − y ≤ . 5 4 2 Graph the solution set of each of these systems of inequalities (6 points each): (not from textbook) x+3≥0 6≤y y − 10 < 0 x<8 3 19. y > −3 7y ≤ −6x + 21 y + 2x ≥ −2 3y + 20x > −30 4 26. 2x − 3y > −9 5x ≥ y − 16 9x + 8 < 7y 5 (not from textbook) x+y <1 x≤y+1 x+y+1>0 1+x≥y 6
