Recall your d = rt, distance = rate * time.
let's say the Eastbound train is going at a rate of "r" mph, since we know the Westbound train is going faster 12 miles more than that, then the Westbound train must be going "r+12".
we also know that after 4 hours, both of them were 760 miles apart, so
John should use his protractor to mark off a 70° angle whose vertex is one end of his 5 cm segment. If John is unsure how to do that, he can look up videos on how to use a protractor.
John could also construct a segment 13.74 cm long at the end of his segment that is perpendicular to the one he has. The angle formed between the other end of his 5 cm segment and the end of the 13.74 cm segment will be 70°.
Another choice John has is to draw an arc from each end of his 5 cm segment that has a radius of 7.3 cm. The point where these intersect over the middle of his segment will form an angle of 70° when a segment is drawn from there to the end of his 5 cm segment.
Another way of writing it is in expanded notation
390. 8 is in the tens place so you go up to nearest ten which is 390
Answer:
the point is (2,3) and the slope is 5
Step-by-step explanation:
The equation is written in point slope form
y-y1 = m(x-x1)
where m is the slope and (x1,y1) is the point
y-3 = 5(x-2)
the point is (2,3) and the slope is 5
