Answer:
you need to find m<G. (knowing that 15x + <G =180.) once you have G's angle measurement, you can solve for <F
80 W divided by 1000 (to convert to kW) = 0.08 kW
The total cost can be calculated by multiplying wattage by time by electricity cost. Note how the units will cancel out, given that 2 weeks is equal to 14 days.
(0.08 kW)(0.5 h/day)(14 days) = 0.56 kWh
Multiply by the cost: ($0.08/kWh)(0.56 kWh) = $0.0448
So the closest answer is the first choice.
You first need to get the equation into y=mx+b form.
y= -3x-1
Now you can use the answer choices and figure out points.
The correct answer when you plug in (2,-7) is C.
-7= -3(2)-1
