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.
