Answer:
H
Step-by-step explanation:
X + 3 = 9-4
First simplify the right side.
9-4 = 5
Now you have x + 3 = 5
Now subtract 3 from both sides:
X = 2
Answer: x = 2
Your answer would be 51.6
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):
then coordinates that Paulo should graph are
(-2, 21)
(-2 means 2 days ago, 21 is the halfway)
