Since we have A(2, 1),
A' has the coordinates (-1, 2).

Short answer: 36.
This is a combination/permutation problem.
To put it simple, a die has 6 sides, there are 7 days but 1 is already determined (12 laps).
So if we multiple the options (sides on a die) × the number of days (6) we get:
6 × 6 = 36 possible outcomes.
To show this we can get
12, 13, 14, 15, 16, 17, 18
12, 13, 14, 15, 16, 17, 19
12, 13, 14, 15, 16, 17, 20
... all the way to
12, 18, 24, 30, 36, 42, 48
Answer:
The number of weekday hours are 5.
Step-by-step explanation:
<em>Let the number of weekday hours be "x".</em>
<em>The total week hours are 26, then number of weekend hours is (26-x) .</em>
<em>The charges for weekdays are $2 per hour and for weekends $10 per hour.</em>
The total money spent is $220.
x = 5.
Thus weekday hours utilized are 5 hours, and weekend are (26-5) 21 hours.
Answer: total distance - 135 = 50 (hours - 2.5)
