Question

:) which of the following is the solution to |x|+5≤1?

Answer 1

Isolating the absolute value term, we find

|x| + 5 ≤ 1   ⇒   |x| ≤ -4

However, the absolute value function maps every number x to a non-negative number, so |x| ≤ -4 is impossible and there is no solution to the inequality.
