Question

What happens if two different inequalities have the same answer but the sign is different? How do I combine them and how do I graph it? Please explain.

Answer 1

When two different inequalities have the same answer but different signs, the solution lies on the boundary line between the inequalities. You can combine them using the 'and' or 'or' operator and graph the combined inequalities by plotting the boundary lines.

Step-by-step explanation:

When two different inequalities have the same answer but different signs, it means that the solution lies on the boundary line between the two inequalities.

To combine these inequalities, you can use the 'and' operator (represented by ∩ or ⋂) if both inequalities must be true, or the 'or' operator (represented by ∪ or ⋃) if either inequality can be true. To graph the combined inequalities, you would plot the boundary lines of each inequality and shade the region that satisfies both inequalities.
