-5 is the solution to the inequality x < -4 and the interval is the x ∈ (-∞, -4) option first is correct.
It is defined as the expression in mathematics in which both sides are not equal they have mathematical signs either less than or greater than, known as inequality.
We have inequality:
x < -4
The solutions to the above inequality will lie in the region (-∞, -4)
x ∈ (-∞, -4)
From the number line, we can mark the region for the above interval (refer attached picture)
Thus, -5 is the solution to the inequality x < -4 and the interval is the x ∈ (-∞, -4) option first is correct.
