Answer:
(d) intersection
Step-by-step explanation:
When given two inequalities, you must determine whether the solution set must satisfy both, or must satisfy either. The key is found in the conjunction associated with the inequalities.
Conjunction
Here, the conjunction is "and," which means the solution must satisfy both inequalities. It also means, the solution set will be the intersection of the solution sets of the different inequalities.
The attached number line shows the first solution set in red, the second solution set in blue, and the "and" (intersection) of those in purple.
The conjunction "or" will signify the solution set is the union of those of the separate inequalities.
