1. inequality, x<−12
2. inequality, B≥ 1/2
1. x<−12
For this inequality, x<−12, it's a strict inequality (<), so it won't include the value of -12.
This means we'll have an open circle at -12 on the number line to represent that it's not included, and the line will extend towards negative infinity.
2. B≥ 1/2
For this inequality, B≥ 1/2 , it's a greater than or equal to inequality (≥). This means it includes the value of 1/2 and everything greater.
This requires a closed circle at 1/2 on the number line, representing that it's included, and the line extends towards positive infinity.
