When you have a point A and then transform it using a linear transformation (like rotation, reflections, etc.), we mark it as A' to say, "This is the point which corresponds to A after the transformations were applied". This establishes a link between the two, even though they may appear to be unrelated to someone looking at the graph.

Answer:
57 mph
Step-by-step explanation:
The relation between speed, time, and distance is ...
speed = distance/time
Using p for the speed of the plane and w for the speed of the wind, we have ...
p + w = 1520/5 = 304 . . . . miles/hour
p - w = 1520/8 = 190 . . . . miles/hour
Subtracting the second equation from the first gives ...
2w = 114
w = 57 . . . . . . divide by 2
The speed of the wind is 57 miles per hour.
Answer: 45
