Q. What interval does this inequality represent?\newline5<x1-5 < x \leq -1\newlineChoices:\newline(A) (5,1](-5, -1]\newline(B) [5,1][-5, -1]\newline(C) [5,1)[-5, -1)\newline(D) (5,1)(-5, -1)
  1. Identify Endpoints: Identify the endpoints of the interval for the inequality -5 < x \leq -1. The endpoints are 5-5 and 1-1.
  2. Check Inclusion: Check whether each endpoint is included in the interval. For -5 < x, 5-5 is not included because the inequality is strict (less than, not less than or equal to). For x1x \leq -1, 1-1 is included because the inequality is non-strict (less than or equal to).
  3. Determine Interval: Determine the interval that the inequality -5 < x \leq -1 represents. Since 5-5 is not included, we use a parenthesis. Since 1-1 is included, we use a bracket. Therefore, the interval is (5,1](-5, -1].
