Ok.graph the 2.3 and the 6.8 as regular decimals, draw a line, annd I dont know how to do the last part. :(
It will be D!!!!!!!!!!!!!!!!!!!!!!!!!
I think the answer is
x < (2b -8) / 3
or
x < 2b/3 - 8/3
Sea level would be 0
So if it is going -12 /ft/s then it is descending 12 feet per second
-120/-12 = 10
The correct answer would be 10 seconds
I hope this helps!
