Answer:
Option A - The distance Train A traveled in 1 h is equal to the distance Train B traveled in 1 h.
Step-by-step explanation:
Given : The distance Train A traveled is modeled by the function
where d represents distance in miles and t represents time in hours.
To find : How does the distance Train A traveled in 1 hour compare to the distance Train B traveled in 1 hour?
Solution :
Distance traveled by Train A in 1 hour is
Distance traveled by Train B in 1 hour is
or for B, we have 324 miles in 4 hours. If that is at a constant speed, it travels 324/4 = 81 miles in one hour
Therefore, The distance Train A traveled in 1 h is equal to the distance Train B traveled in 1 h.
Hence, Option A is correct.

Replace all occurrences of + − with a single − . A plus sign followed by a minus sign has the same mathematical meaning as a single minus sign because 1 ⋅ − 1 = − 1 2 − 2 c − 9 c 2
Answer:
Step-by-step explanation:
-(-2 + 3x - 1/2) = -( -2 - 0.5 + 3x)
= -(-2.5 + 3x)
= -1*(-2.5) + (-1)*3x
= 2.5 - 3x
2.5 - 3x is not equivalent to 2.5 + 3x
