Answer:
The maglev train can reach a top speed of 431 km/h (268 mph).
Step-by-step explanation
I did the math and (6,26) is the correct answer.
Let's just start with x=20 and then do some algebra to it to make it all complicated
x = 20
2 * x = 2 * 20
2x = 40
2x - 13 = 40 - 13
2x - 13 = 27
You are right about the domain.
