Answer:
First blank: non-viable solution because the costs aren't less than the revenue
Second blank: viable solution because the costs are less than the revenue
Step-by-step explanation:
First: Insert the x into the equation and work it out to see if it is less than the y.
(30,90) x=30 y=90
y=1.5(30)+45
y=45+45
y=90
Non-Viable
Second: Insert the x into the equation and work it out to see if it is less than the y.
(60,160) x=60 y=160
y=1.5(60)+45
y=90+45
y=135
Viable
(hope this helps :P)

Answer:
Step-by-step explanation:
To answer this problem, we must bear in mind that the express train travels 3 times faster than the freight train.
If we call F the distance that the freight train travels and we call E at the distance that the express train travels, we must have the distance between them after 15 minutes it must be 30 miles.
So
We also know that:
Since the express train travels 3 times faster than the freight train.
So, like both equations, we have to:
Then miles in the opposite direction.
This is the distance you traveled in 15 minutes.
Therefore, the speed of the express train () is the distance traveled between the time it did
