Which graph represents the solutions to the inequality 2x-6<4?

Answer:
D
Step-by-step explanation:
solving the inequality
Inequalities of the type | x | < a always have a solution of the form
- a < x < a
For | 2x - 6 | < 4 then solution is
- 4 < 2x - 6 < 4 ( add 6 to all 3 intervals )
2 < 2x < 10 ( divide all 3 intervals by 2 )
1 < x < 5 → graph D
The open circles at the ends of the blue line indicate up to but not including these points.
[tex]|2x-6| < 4\iff2x-6<4\ \wedge\ 2x-6>-4\qquad\text{add 6 to both sides}\\\\2x<10\ \wedge\ 2x>2\qquad\text{divide both sides by 2}\\\\\boxed{x<5\ \wedge\ x>1}\to1< x<5[/tex]
≤, ≥ - full circle
<, > - open circle
