so b ≥1

Answer 2

B - 2 > -1

This is an inequality equation. It is not equal to a specific number. There are a lot of numbers that can be considered as long as it makes the inequality equation TRUE.

b - 2 > -1
   + 2   + 2
b      > 1

b is a number that is at least 1 or greater than 1.

b = 1

1 - 2 > -1
   - 1 > -1  True. Had the sign been only >  and not >, 1 would not be a value of b.

b = 2
2 - 2 > -1
0 > -1 True.
