1. In a xy plane at what 2 points dpes the line y = (x+a)(x+b) intersec the x-axis. a. a+b=-1 b. the graph intersects the y axis at (0,-6) 2. A decorater has to choose 2 chairs and 2 tables from a warehouse such that all are diffrent. if there are 5 diffrent chairs and 150 combinations possible, how...

xy = 0
i.e x=0 or y = 0
so a. x!0 then y = 0, so |x-y| will be greater than 0
frm b. y=0 so x!0, so |x-y| again > 0.
so D but ans is A .. ??

stmt 2 - chose m = -3 and n = -2 m-n = -1 > n (-2) m/n 3/2 >1
next chose m = -2 and n = -3; m-n = 1 (> n) and 2/3 < 1
togetehr they make no sense so ans = E
