Solutions of which of the inequalities comprising a system in variable x are represented on number lines as given below, (black color is taken in consideration)
The correct option is D
x ∈ (–∞, – 4) ∪ [3, ∞)
Given number lines:
So, the solution of first number line and second line is R−[−4,3) and R−[−3,1)
Thus, required solution is {R−[−4,3)}∩{R−[−3,1)}
=R−{[−4,3)∪[−3,1)}
=R−{[−4,3)}
∴x ϵ (−∞,−4) ∪ [3, ∞)
