Question

question
solve the inequality and graph the solution on the line provided.
3x + 9 ≥ -15
answer attempt 1 out of 2
< > ≤ ≥ or
inequality notation: x
number line:
-12 -10 -8 -6 -4 -2 0 2 4 6 8 10 12

Explanation:

Step1: Subtract 9 from both sides

$3x+9 - 9\geq - 15 - 9$
$3x\geq - 24$

Step2: Divide both sides by 3

$\frac{3x}{3}\geq\frac{-24}{3}$
$x\geq - 8$

Answer:

Inequality Notation: $x\geq - 8$
Number Line: Mark a closed - circle at - 8 (because of $\geq$) and shade to the right.
