Question

the movement of the progress bar may be uneven because questions can be worth more or less (including zero) depending on your answer. which graph represents the solution to 7x > 21 or 6x + 9 < 21? four number line graphs with options

Explanation:

Step1: Solve \(7x > 21\)

Divide both sides by 7: \(x > \frac{21}{7} = 3\)

Step2: Solve \(6x + 9 < 21\)

Subtract 9: \(6x < 21 - 9 = 12\)
Divide by 6: \(x < \frac{12}{6} = 2\)

Step3: Analyze "or" solution

"Or" means all \(x < 2\) or \(x > 3\). The graph should have an open circle at 2 (shading left) and open circle at 3 (shading right), matching the last option (blue lines left of 2 and right of 3, open circles at 2 and 3).

Answer:

The graph with open circles at 2 and 3, shading left of 2 and right of 3 (the fourth option in the list).
