Answer:
- X Greater-than-or-equal-to 12
- A closed circle is used on the graph.
- The arrow on the graph points right.
Step-by-step explanation:
This one-step inequality can be solved by adding the opposite of the constant that is added to x. A number line graph of the solution is attached.
x -2.6 ≥ 9.4
x ≥ 12.0 . . . . . . add 2.6 to both sides
The "greater than" relation means that numbers larger than 12 will be included in the solution set. Shading of the number line will be to the right of 12.
The "or equal to" relation means that 12 itself is included in the solution set. This is indicated by a closed circle at 12 on the graph.
The true statements are ...
- X Greater-than-or-equal-to 12
- A closed circle is used on the graph.
- The arrow on the graph points right.
