Step-by-step explanation:

Answer 2

Answer:

(True or False) The inequality |x + 1| < 0 has no solution.

Solution

The absolute value of a real expression is either positive or equal to zero. Therefore there is no value of x that makes |x + 1| negative and therefore |x + 1| < 0 is never true and the statement "The inequality |x + 1| < 0 has no solution" is TRUE.
