Answer:
To determine which of the given inequalities are equivalent to the inequality x - b < 3, where b is a constant, we can analyze each option:
1. x - b - 3 < 0:
This inequality is equivalent to x - b < 3 because if you add 3 to both sides, you get x - b < 3.
2. x < 3 - b:
This inequality is also equivalent to x - b < 3 because you can add b to both sides, giving x - b < 3.
3. 0 > b - x + 3:
This inequality is not equivalent to x - b < 3. It's the reverse of x - b > -3, which is not the same as x - b < 3.
4. -3:
This is not an inequality; it's just a constant value.
So, the inequalities that are equivalent to x - b < 3 are:
1. x - b - 3 < 0
2. x < 3 - b
