How do you say y ≥ -5 ?
You would say "y is greater than or equal to negative five."
Which graph shows x > 12 in blue?
I apologize, but as a text-based AI model, I am unable to display or create visual content like graphs. However, I can explain how to represent the inequality x > 12 on a graph.
To represent x > 12 on a graph, you would draw a blue line or shade the region to the right of a vertical line passing through the number 12. The line should be dashed to indicate that it does not include the value 12 itself (as the inequality is strict, not inclusive).
To clarify, any point to the right of the vertical line at x = 12 would satisfy the inequality x > 12, and those points would be shaded or highlighted in blue on the graph.
