Question

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

Explanation:

Step1: Isolate the term with x

Subtract 9 from both sides of the inequality $3x + 9\geq - 15$.
$3x+9 - 9\geq - 15 - 9$
$3x\geq - 24$

Step2: Solve for x

Divide both sides of the inequality $3x\geq - 24$ by 3.
$\frac{3x}{3}\geq\frac{-24}{3}$
$x\geq - 8$

Answer:

Inequality Notation: $x\geq - 8$
Number Line: Place a closed - circle at - 8 (because the inequality is $\geq$) and draw a line to the right of - 8.
