Question

solve and graph the following inequality. a + 1 ≤ - 11 select the correct choice below and fill in the answer box to complete your choice. a. the solution is {a | a ≤ }. b. the solution is {a | a > }. c. the solution is {a | a < }. d. the solution is {a | a ≥ }.

Explanation:

Step1: Isolate the variable a

Subtract 1 from both sides of the inequality $a + 1\leq - 11$.
$a+1 - 1\leq - 11 - 1$

Step2: Simplify the inequality

$a\leq - 12$

Answer:

A. The solution is $\{a\mid a\leq - 12\}$
