X=80°
Answer:
10/13 ≤ x < 18/13
Step-by-step explanation:
-1 ≤ 13x - 11 < 7
If a ≤ u < b then a ≤ u and u < b
⇒ -1 ≤ 13x - 11 and 13x - 11 < 7
-1 ≤ 13x - 11
Add 11 to both sides: 10 ≤ 13x
Divide both sides by 13: 10/13 ≤ x
13x - 11 < 7
Add 11 to both sides: 13x < 18
Divide both sides by 13: x < 18/13
Combine the intervals
10/13 ≤ x < 18/13
The answer to this is false.
