Given:
∣3x−2∣≥4
Which of the following statements is necessarily true?
To solve the inequality ∣3x−2∣≥4, we separate it into:
3x−2≥4 or 3x−2≤−4.
For 3x−2≥4, add 2 to both sides:
3x≥6
Divide by 3:
x≥2
For 3x−2≤−4, add 2 to both sides:
3x≤−2
Divide by 3:
x≤−32
Therefore, the solution is x≥2 or x≤−32.
x≥2 or x≤−32
