Q. What inequality represents this interval?\newline(−∞,9](-\infty, 9]\newlineChoices:\newline(A) x≥9x \geq 9\newline(B) x<9x < 9\newline(C) x>9x > 9\newline(D) x≤9x \leq 9
  1. Identify Endpoints: Identify the endpoints of the interval \$-\infty, 9\]. The endpoints are −∞-\infty and 99.
  2. Check Inclusion: Check whether the finite endpoint is included or not. In the interval (−∞,9](-\infty, 9], 99 is included because of the closed bracket.
  3. Determine Inequality: Determine the inequality that the interval (−∞,9] (-\infty, 9] represents. Since −∞ -\infty cannot be included as it is not a finite value and 9 9 is included, the inequality is x≤9 x \leq 9 .
