The solution to an inequality is (–∞, 6.5]. Is 6.5 a solution to the inequality? Explain your answer. The solution includes numbers from negative infinity to 6.5. Because a bracket is used, the solution does not include 6.5. The solution includes numbers from 6.5 to infinity. Because a parenthesis is used, the solution does not include 6.5. The solution is the point (–∞, 6.5). Because a bracket is used, 6.5 is a solution to the inequality. The solution includes numbers from negative infinity to 6.5. Because a bracket is used, the solution includes 6.5.
