The average = 1/2 (sum of the two bases) = 1/2 ( 16.8 + 6.9) = 11.85 yards
Ur not dumb!!! i graphed the line for u here. i suggest watching some khan academy videos for extra practice!
Step-by-step explanation:
For no 1...
The range is [ -9, -7, 1]
For no 2....
The range is [-12, -10, -2]
For no 3.....
The range is [-11, -8, 4]
I got 20,737 but I could be wrong so I will attach my algorithm and work.
You have to move variables on one side and constants on the other
aby - b + b = c + b
aby = c + b
y = (c + b)/ab
