A 120 watt light bulb uses about 0.1 kilowatt of electricity per hour.if electricity costs $0.20 per kilowatt hour.
Let's solve how much does it cost to have a bulb on
for an hour.
=> 120 watt = 0.1 kilowatt per hour which costs 0.20 per kilowatt per
=> 0.1 kilowatt per hour * 0.20 = 0.02 dollars in an hour.
Answer:
2(17-27x)
Step-by-step explanation:
Since the question was incomplete this is the only answer I have for you.
If you were looking for the answer of X I would need a answer for the equation
Anyways... you want to factor out 2 from the expression since there are two numbers
Once you factored out the two (divide each number by 2) you'll get:
2(17-27x)
Ohhhh nasty ! What a delightful little problem !
The first card can be any one of the 52 in the deck. For each one ...
The second card can be any one of the 39 in the other 3 suits. For each one ...
The third card can be any one of the 26 in the other 2 suits. For each one ...
The fourth card can be any one of the 13 in the last suit.
Total possible ways to draw them = (52 x 39 x 26 x 13) = 685,464 ways.
But wait ! That's not the answer yet.
Once you have the 4 cards in your hand, you can arrange them
in (4 x 3 x 2 x 1) = 24 different arrangements. That tells you that
the same hand could have been drawn in 24 different ways. So
the number of different 4-card hands is only ...
(685,464) / (24) = <em>28,561 hands</em>.
I love it !
First we need to find the slope of the function
The slope of a function is equal to

So now we plug this into the equation and find the slope (M will represent the slope)

So the slope is -3/2
Now we can use point-slope form.
Point slope form is represented by

So when we plug in our values we get

So the equation is
Y = -3/2X-7/2
