Answer:
Slope: -3, apparent point: (-1, -2)
Step-by-step explanation:
Point-slope form means the equation of a line is given in the form of y - y1 = m(x - x1), where x1 and y1 are coordinates of a point that lies on the line and m is its slope. Keeping this in mind while looking at the given equation, you can see that -3 is where m goes, meaning the slope is -3. You can also see that 1 and 2 are in the places where - x1 and - y1 go (don't forget those minus signs!) so you take those two and make them an ordered pair for your apparent point of (-1, -2).
Answer: y=24
Step-by-step explanation:180-49=131 131-32=96, 96 devided by 4 is 24
Answer:
The best option is C
Step-by-step explanation:
I believe this because it is the cheapest amount of money PER PENCIL. For a it is $0.37 per pencil, for b it is $0.35 per pencil, for c it is $0.33 per pencil, and for d it is $0.40 per pencil. I did these calculations by taking the amount of money and dividing by the amount of pencils. So, for what the question asks, the answer would be C because it wants the one with the least amount of money PER PENCIL.
Answer:15
Step-by-step explanation:
Given
Craftsman sell 10 Jewelry set for $500 each
For each additional set he will decrease the price by $ 25
Suppose he sells n set over 10 set
Earning![=\text{Price of each set}\times \text{no of set}](https://tex.z-dn.net/?f=%3D%5Ctext%7BPrice%20of%20each%20set%7D%5Ctimes%20%5Ctext%7Bno%20of%20set%7D)
Earning ![=(500-25n)(10+n)](https://tex.z-dn.net/?f=%3D%28500-25n%29%2810%2Bn%29)
![E=5000+500n-25n^2-250n](https://tex.z-dn.net/?f=E%3D5000%2B500n-25n%5E2-250n)
differentiate to get the maximum value
![\frac{dE}{dn}=-50n+250](https://tex.z-dn.net/?f=%5Cfrac%7BdE%7D%7Bdn%7D%3D-50n%2B250)
Equate
to get maximum value
![-50n+250=0](https://tex.z-dn.net/?f=-50n%2B250%3D0)
![n=\frac{250}{50}](https://tex.z-dn.net/?f=n%3D%5Cfrac%7B250%7D%7B50%7D)
![n=5](https://tex.z-dn.net/?f=n%3D5)
Thus must sell 5 extra set to maximize its earnings.
Fg - 9h = 10j
Add -9h to the other side
fg = 10j - 9h
Divide by f on the other side
g = 10j -9h
