2. A plane traveled from California and back. It took one hour longer on the way out than it
did on the way back. The plane's average speed out was 300 mph. The average speed on the
way back was 350 mph. How many hours did the trip out take?
O A. 13 hours
B. 7 hours
O C. 8 hours
OD. 6 hours

Option D is the correct answer.

Step-by-step explanation:

the time out.

Time taken for back = t-1

We have plane's average speed out was 300 mph and average speed on the way back was 350 mph.

That is

Dividing both equations

Time taken for back = t-1 = 7-1 = 6 hours.

1/800 is the right answer

step-by-step explanation:

let

we know that

the y-intercept is the y-coordinate of the point when the value of x is equal to zero

so

the y-coordinate of the point a is the y-intercept

the answer part a) is

the value of y-intercept is

part b) find the slope m

we know that

the value of the slope is equal to

substitute the values

therefore

the answer part b) is

the value of the slope is equal to

the general answer is

the slope is

the value of y-intercept is
