Y - y₁ = m(x - x₁)
y - ¹/₆ = ³/₅(x - 0)
y - ¹/₆ = ³/₅(x) - ³/₅(0)
y - ¹/₆ = ³/₅x - 0
<u> + ¹/₆ + ¹/₆
</u> y = <u><em /></u><em />³/₅x + ¹/₆
y = ³/₅(0) + ¹/₆
y = 0 + ¹/₆
y = ¹/₆
6x + 9 < 63
Subtract 9 from both sides.
6x < 54
Divide 6 by both sides.
x < 9
Answer:
19338 kWh
Step-by-step explanation:
In Arizona, electricity cost eleven cents per kilowatt-hour.
The average home uses 66 million BTU per year i.e. 66000000 BTU per year.
Now, it is given in the question that 1 BTU is equivalent to 0.000293 kWh.
So, the average home uses (66000000 × 0.000293) = 19338 kWh per year.
Therefore, the number of kilowatt-hours used per year will be 19338. (Answer)
