Answer:
The solution of the inequality is -2 < t < 3 and the graph is the attachments
Step-by-step explanation:
In order to solve this inequality you can use this rule if a < u < b then a < u and u < b, so -14 < 7t and 7t < 21.
The first inequality:
-14 < 7t = 7t > -14 = 7t/7 > -14/7 = t > -2
The second inequality:
7t < 21 = 7t/7 < 21/7 = t < 3
Merge overlapping intervals gives you the solution:
-2 < t < 3
The solution to this inequality is the set of all real numbers t that are less than 3, and greater than -2 not including -2 and 3. The solution is represented by a line.
