Question

solve each inequality, graph its solution set and write the solution set in interval notation.
3 |3x-5| ≥ 66. I get x≥9 , x≥ -17/3 how to write in interval notation?

Answer 1

3|3x - 5| ≥ 66
|3x - 5| ≥ 22
3x ≥ 27
x ≥ 9

3x - 5 ≤ -22
3x ≤ -17
x ≤ -17/3
x ≤ -17/3 or x ≥9
Interval notation is written using [] and ()
[-∞, -17/3] U [9, ∞]
