Answer:
Option B
Step-by-step explanation:
To solve these kind of question we just simply keep on inserting the values of x and if we get the required value of y that is in the table that equation is our answer, For example lets take Option A,
y = 8x
If we insert x = 0 we get,
y = 8(0)
y=0
but in the table it says we get 14 so option A is incorrect
Like this we keep checking for more values and all the values of x satisfy our equation in Option B like this,
and so on so Option B is the answer
Answer: 6,987,000 pounds fo CO₂ per kWh.
Step-by-step explanation: <u>Quilowatt</u>-<u>hour</u> <u>(kWh)</u> is a unit of energy that measures the amount of energy expended in 1 hour.
The AC uses 850 Watts, which in kW is 850,000 kW
If you leave the AC on for 6 hours, it will consume
850,000(6) = 5,100,000 kWh
Eletricity produces 1.37 pounds of CO₂ per kWh, then in 5,100,000 kWh:
1.37 .(5,100,000kWh) = 6,987,000 pounds
If you open a window for 6 hours, you would keep 6,987,000 pounds of CO₂ for entering the atmosphere.
