To solve the inequalities, let’s break them down one by one.
(a)
This absolute value inequality can be rewritten as a compound inequality:
We can split it into two separate inequalities:
  1. Lower Bound:
    Adding 5 to both sides:
    Dividing by 4:
  2. Upper Bound:
    Adding 5 to both sides:
    Dividing by 4:
Combining both results, we have:
(b)
Similarly, this absolute value inequality can be rewritten as:
We will tackle both sides of the inequality:
  1. Lower Bound:
    Adding 1 to both sides:
    Since is always greater than or equal to 0 for real numbers, this inequality is always satisfied.
  2. Upper Bound:
    Adding 1 to both sides:
    Taking the square root of both sides, keeping in mind both positive and negative roots:
Combining these results, we find that the values satisfying both inequalities are:

Final Results:

  • For inequality (a):
  • For inequality (b):
Thus,
  • Overall Solution for (a):
  • Overall Solution for (b):
