Question

solve and graph the inequality. write the solution set using interval notation. 5) a - 3 < -9

Explanation:

Step1: Isolate the variable a

Add 3 to both sides of the inequality $a - 3<-9$.
$a-3 + 3<-9 + 3$

Step2: Simplify the inequality

$a<-6$

Answer:

The solution - set in interval notation is $(-\infty,-6)$. To graph it, draw an open circle at - 6 on the number - line (since the inequality is strict, $a
eq - 6$) and shade the line to the left of - 6.
