Step-by-step explanation:
well it represents
-1 < X ≥ 3
so answer is 0 1 2 3
I'd say (a) = 52.5 minutes or 52 minutes and 30 second
(b) = 45 minutes
It would be the 2nd answer....your initial value (read from the left of the line graph) is 4.....following the line to the first even point you can see it has dropped 3 for the 4 points it has moved to the right....giving -3/4 as the rate of change.
If you add all of the numbers together the answer your going to get is 17+32+28 which equals 77
The answer is 8 because when you replace x by 8 it equals 24
