<em>A. x ≤ - 9 or x ≥ 9</em>
- Step-by-step explanation:
<em>x² ≥ 81</em>
<em>| x | ≥ 9</em>
<em>x ≥ 0 => x ≥ 9 => x ∈ [ 9 ; + oo)</em>
<em>x < 0 => x ≤ - 9 => x ∈ ( -oo ; - 9 ]</em>
<em>x ∈ ( -oo ; - 9 ] ∪ [ 9 ; + oo)</em>
Answer:
The journey from from Newport to Shrewsbury is around 1 hour and 37 minutes by train. To find the time you reach Shrewsbury, add 1 hour and 37 minutes to the time you catch the train (4:58).
1:37+4:58
5:95
Since there are only 60 minutes in an hour, add another hour to the time and subtract 60 minutes from the time.
6:35
You would reach Shrewsbury at 6:35.
Hope this helps! :)
