Answer:
a) x + 8 ≥ 6
Explanation:
x + 8 ≥ 6
Step 1: Subtract 8 from both sides
x + 8 - 8 ≥ 6 - 8
Step 2: Simplify
x ≥ -2
And since the symbol is greater than, we use a closed circle. Also, since the inequality is like an arrow pointing to the right, we draw the arrow going to the right.
Here are what the inequality symbols mean:
> = Greater than
≥ = Greater than or equal to
< = Less than
≤ = Less than or equal to
Open circles are used for numbers that are less than or greater than (< or >). Closed circles are used for numbers that are less than or equal to and greater than or equal to (≤ or ≥).
