Answer:
C. 20 seconds
Step-by-step explanation:
We want to know when y=0
The first y is when it started and the second y=0 is when it stops
Looking at the graph y=0 at x=0 and y=0 at x=20
The fan started at time 0 and stopped at 20 seconds
The correct answer is letter C; -6,
-5 2/5 or -27/5 and -4 1/5 or -21/5.
You can find this answers by substituting 1, 4, and 10 into the letter n.
Then you follow the operational order to get the answer.
1.2x + 3.4 = 10.6
subtract 3.4 from each side
1.2x = 7.2
divide each side by 1.2
x = 6
