A.
2/3A=-24
time both sides by 3/2
A=-72/2
A=-36
B.
20=-B/0.2
times both sides by 0.2
4=-B
times -1
-4=B
distance between 2 points x and y is |x-y|
so
distance between A and B is distance between -4 and -72 or
|-72-(-4)|=|-72+4|=|-68|=68
the distance is 68
Answer:
![y =mx +bx](https://tex.z-dn.net/?f=%20y%20%3Dmx%20%2Bbx)
Where y is the total amount earned, m the amount for each extended warranty and b the fixed cost and x the total amount of TVs
For this case the value of x = 16 since we have 16 Tvs with extended warranties and we can do this:
![1200 = 15*16 +16b](https://tex.z-dn.net/?f=%201200%20%3D%2015%2A16%20%2B16b)
and solving for b we got:
![b= \frac{1200-15*16}{16}= 60](https://tex.z-dn.net/?f=%20b%3D%20%5Cfrac%7B1200-15%2A16%7D%7B16%7D%3D%2060)
And then we can conclude that she earns 60 for each TV
Step-by-step explanation:
For this case we can set a linear model like this:
![y =mx +bx](https://tex.z-dn.net/?f=%20y%20%3Dmx%20%2Bbx)
Where y is the total amount earned, m the amount for each extended warranty and b the fixed cost and x the total amount of TVs
For this case the value of x = 16 since we have 16 Tvs with extended warranties and we can do this:
![1200 = 15*16 +16b](https://tex.z-dn.net/?f=%201200%20%3D%2015%2A16%20%2B16b)
and solving for b we got:
![b= \frac{1200-15*16}{16}= 60](https://tex.z-dn.net/?f=%20b%3D%20%5Cfrac%7B1200-15%2A16%7D%7B16%7D%3D%2060)
And then we can conclude that she earns 60 for each TV
Answer:
Look at the place after the thousandths, it is less than 5.
0.8344
So don't add +1 to the thousandths place.
Rounded to the nearest thousandths would be:
<h2>0.834</h2>
