Final answer:
A number line for x>=-3 would include a closed circle at -3, -2, -1, etc.
Step-by-step explanation:
A number line for x≥-3 would include:
A) A closed circle at -3, -4, -5, etc.
B) An open circle at -3, -4, -5, etc.
C) A closed circle at -3, -2, -1, etc.
D) An open circle at -3, -2, -1, etc.
The correct answer is C) A closed circle at -3, -2, -1, etc.
When x≥-3, it means that x is equal to or greater than -3. To represent this on a number line, we use a closed circle at -3 (inclusive) and draw the line to the right to represent numbers greater than -3.
