Solution set for the inequality $\left|\frac{3x-2}{2}\right|≥3$ includes the intervals : A. $\left(\frac{8}{3}, ∞\right)$ B. $\left[\frac{8}{3}, ∞\right)$ C. $\left[\frac{4}{3}, ∞\right)$ D. $\left(\frac{4}{3}, ∞\right)$ E. $\left(-∞, \frac{-4}{3}\right]$ Choose the correct answer from the options given below : |
A and D only B, C and E only B and E only C only |
B and E only |
The correct answer is Option (3) → B and E only $\left|\frac{3x-2}{2}\right|≥3$ $|3x-2|≥6$ Case 1: $x≥\frac{2}{3}$ $3x-2≥6$ $3x≥8$ $x≥\frac{8}{3}$ $⇒\left[\frac{2}{3},∞\right)$ Case 2: $x≤\frac{2}{3}$ $-3x+2≥6$ $-3x≥4$ $x≤-\frac{4}{3}$ $⇒\left(-∞,-\frac{4}{3}\right]$ |
