Answer:
A man drove x miles per hour for 3 hours and (2x-60) miles per hour for the next 4.75 hours.Express the total distance traveled in terms of x.
Total distance covered by the man in terms of 'x' = (12.5x-285)miles
Step-by-step explanation:
Given:
Speed of a man = 'x' miles/hour
Time taken =
hour
So, distance = product of speed and time.
Distance covered in term of 'x' 
Now,
Speed =
miles/hour
Time taken=
hours
Distance
= 
= 
=
miles
Total distance covered by the man = Summation of
and 
= 
=
miles
So the total distance covered by the man in terms of 'x' = (12.5x-285) miles.
Answer:
147
Step-by-step explanation:
Average rate of change is given by the total rise over total run.

So,
total rise = 377 - 83 = 294
total run = 2
average rate of change = 
The answer is c, y=2. if you look at the graph you can see that where x=-2 the line intersects the y axis at +2.
Answer:
