If they are traveling in different directions then you add up the two mi/hr then whatever you have to multiply the sum by is the number of hours. By the way the sender is 4 hours.

Answer:

(-2,21)

Step-by-step explanation:

2 days ago, Paulo's commute time was halfway between his commute times 8 and 9 days ago.

8 days ago means that x-coordinate -8 represents this day. Count 8 units to the left and find that when x = -8, y = 24 minutes.

9 days ago means that x-coordinate -9 represents this day. Count 9 units to the left and find that when x = -9, y = 18 minutes.

Find halfway commute time between points (-8,24) and (-9,18):

y=\dfrac{24+18}{2}=\dfrac{42}{2}=21,

then coordinates that Paulo should graph are

(-2, 21)

(-2 means 2 days ago, 21 is the halfway)

If g(x) = 3x - 5, then g -1(x)=<br><br><br><br> 3x + 5
ludmilkaskok [199]

Hey!

-------------------------------------------------

This just shows to substitute all of x with -1.

g(-1) = 3(-1) - 5

g(-1) = -3 - 5

g(-1) = -8

-------------------------------------------------

Hence, the answer is -8!

-------------------------------------------------

Hope This Helped! Good Luck!
