Question

solve for a and graph the solution on the number line below. -7 ≤ -12 + a
answer attempt 1 out of 2
inequality notation:
number line

Explanation:

Step1: Isolate the variable

Add 12 to both sides of the inequality $-7\leq - 12 + w$.
$-7+12\leq -12 + w+12$.

Step2: Simplify the inequality

$5\leq w$, which can also be written as $w\geq5$.

Answer:

Inequality Notation: $w\geq5$
Number - Line: On the number line, place a closed circle at 5 (since the inequality is $\geq$) and draw a line extending to the right.
