Answer:
c. x > 7 / 5 or x < 1 / 5
Step-by-step explanation:
2 | 5x − 4 | > 6
| 5x - 4 | > 3
- 5x -4 > 3 ⇒ 5x > 7 ⇒ x > 7/5
- 5x -4 < -3 ⇒ 5x < 1 ⇒ x < 1/5
So combining the 2 above we get:
- x > 7/5 or x < 1/5
Correct choice is c.
Answer:
x>7/5 or x <1/5
Step-by-step explanation:
2 | 5x − 4 | > 6
Divide by 2
2/2 | 5x − 4 | > 6/2
| 5x − 4 | > 3
There are two solutions one positive and one negative ( the negative flips the inequality)
5x-4 >3 or 5x-4 < -3
Add 4 to each side
5x-4 +4>3+4 or 5x-4+4 < -3+4
5x >7 or 5x <1
Divide by 5
x>7/5 or x <1/5
