Answer:
There are no coefficients.
Step-by-step explanation:
150 books-86 books= 64 books.
We originally have 86 books, so the percent of increase is:
64 books/ 86 books* 100%= 74.42%
The percent of increase is 74.42%~
Answer: y= 6x +14 and you would be able to feed 6 people cause when the graph starts the first 4 already counted for and since 6 is needed for each addition person that would mean 2 more people can be fed cause 26-14=12 and 12 divided by 6 is 2
Slope intercept form is y= m(x) + b
His average speed for the first trip is 43 mph
Since Brian's average speed is x and he travels the first part for 215 miles in time t.
So, his distance d = xt
Also, the travels 75 more miles at a speed of 15 mph.
Since distance = speed time, the time he takes to cover this distance is
t' = distance/speed = 75 mi/15 mph = 5 hours
Since he covers both distances in the same time, we have that t = t' = 5 hours.
So, his average speed for the first trip x = d/t
= 215 mi/5 h
= 43 mph
His average speed for the first trip is 43 mph
