Answer:
y= 2 + 0.23x
Step-by-step explanation:
Giving the following information:
A text message plan costs $2 per month plus $0.23 per text.
<u>First, we need to structure the total cost formula:</u>
<u></u>
y= total cost
x= number of text messages
y= 2 + 0.23x
<u>Now, we can calculate the total cost for any number of text:</u>
x= 200
y= 2 + 0.23*200
y= $48
Step-by-step explanation:
I don't understand, why there is this segment about the 0 degrees Kelvin.
any material, water or the glass the water is in, or the air, or the floor or the wall : the higher the temperature (the scale does not matter, as long both temperatures use the same), the more energy it contains (the faster the particles in that substance are moving/vibrating).
therefore a glass of water with 80 degrees will have much more energy than one with 20 degrees.
the same way an aluminum can (the actual name of that material is aluminium, but Americans seemingly cannot pronounce that) with 30 degrees has more energy than one with 20 degrees.
