In a number line is the solution is the shaded area at right of x=5 (open circle, the value of x=5 is not included in the solution)
Part 2) we have
The solution is the interval (-∞,5)
All real numbers less than 5
In a number line is the solution is the shaded area at left of x=5 (open circle, the value of x=5 is not included in the solution)
Part 3) we have
The solution is the interval [5,∞)
