C. Since the data is going down by -8, and it starts at +45
Answer:
y = 250x + 1000
Step-by-step explanation:
we know, it is a linear function.
so, y = ax + c
we have multiple data points all on the line.
(4,2000)
2000 = a×4 + c, => c = 2000 - a×4
(7,2750)
2750 = a×7 + c
=> 2750 = a×7 + 2000 - a×4 = a×3 + 2000
=> 750 = a×3
=> a = 250
=> c = 2000 - 250×4 = 2000-1000 = 1000
Notice the proportions below. Keep in mind that 1 hour is 60 minutes.
33%= 0.33 there are 24 hours in a day 24 x 0.33 or 33% equals 7.92 which rounds to 8 hrs a day
