Question

solve the inequality and graph the solution on the line provided. -9 + 7x ≤ 40 answer < > ≤ ≥ or inequality notation: . number line:

Explanation:

Step1: Add 9 to both sides

$-9 + 7x+9\leq40 + 9$
$7x\leq49$

Step2: Divide both sides by 7

$\frac{7x}{7}\leq\frac{49}{7}$
$x\leq7$

Answer:

$\leq$, $x\leq7$
To graph on the number - line: Place a closed circle at 7 (because the inequality is $\leq$) and shade to the left of 7.
