If the representation of an inequality on a number line features a hollow circle with an arrow pointing leftward, what symbol would be used in the inequality itself?
The symbol used would be "<" or "less than".
If the representation of an inequality on a number line features a hollow circle with an arrow pointing leftward, the inequality symbol used would be "<". This symbol represents "less than". The hollow circle indicates that the number at the endpoint is not included in the solution set.
If the representation of an inequality on a number line features a hollow circle with an arrow pointing leftward, it is indicating that the number on the number line is not included in the solution set. To determine the symbol used in the inequality itself, we can follow these steps:
1. Start by determining the direction of the arrow on the number line. In this case, the arrow is pointing leftward.
2. Next, consider what this direction represents in terms of the inequality sign:
- If the arrow is pointing leftward, it means that the solution set includes all values less than the number indicated by the arrow. To express this in the inequality itself, you would use the less than symbol (<).
Therefore, the symbol used in the inequality itself would be the less than symbol (<).
