Try to rewrite this inequality as a compound inequality.
{ t | 1 ≤ t ≤ 11 }
This compound inequality means that the distance between t and 6 is greater than or equal to - 5 and less than or equal to 5. t-6 ≤ 5 and t-6 ≥ -5 Let's isolate t in both of these cases before determining the solution set.
The solution to this type of compound inequality is the overlap of the solution sets. Let's recombine our cases back into one compound inequality. First Solution Set:& t ≤ 11 Second Solution Set:& 1 ≤ t Intersecting Solution Set:& 1 ≤ t ≤ 11
