vvishal Posted June 27, 2015 Share Posted June 27, 2015 (edited) PLEASE HELP ME TO WORK OUT THESE PROBLEMS... (1) if r>t , r (a) r>0 and t (b) r>-1 and t © r (d) r1 (e) r>1 and t (2) if x and y are the integers such that 0 (a) xy (b) x>3 © x>4 (d) x+y=5 (e) x-y (3) if line segment AD has midpoint M1 and the line segment M1D has midpoint M2 ,what is the value of (M1D)/(AM2). (a)3/5 (b)2/3 ©1/3 (d)2/5 (e)1/2. Edited June 27, 2015 by vvishal Quote Link to comment Share on other sites More sharing options...

YaSvoboden Posted July 2, 2015 Share Posted July 2, 2015 If you have the answers, that would be great. 1. b) rt=1 =>r=1/t Because r=1/t and r>t, r has to fall between -1 and 0 and t is less than -1. the constraint that r 2) I don't think any of these are right. If you are restricted to positive integers, then e is correct. Counterexamples: a, b, c, and d) x=2, y=4 e) x=12, y=-3 3) 2/3 Just think of it as a 4 unit line segment. A--M1-M2-D. You can see there are 2 units between M1 and D and 3 between A and M2. Quote Link to comment Share on other sites More sharing options...
