the question then goes on to say, "if the solutions are denoted by t1 and t2 where t1 < t2, find t1 and t2?"

what are the answers? - Nov 12th 2010, 04:50 PMskeeter

one more time ...

evaluate each value of t in your calculator ... check the results with your graph. - Nov 12th 2010, 05:27 PMmadmax29
so because the summary of the statement is a just a as apposed to , then the ones with are the real answers? would this statement be correct?
