Answer:
y = 2x - 20
Step-by-step explanation:
Simplfy 2 (x-1)
y + 18= 2x - 2
move all terms contain "y" to the left side
y = 2x - 20

Answer: No solutions (system is inconsistent)</h3>
=====================================================
Explanation:
Rearrange the first equation into ![-x^2+y^2 = 16](https://tex.z-dn.net/?f=-x%5E2%2By%5E2%20%3D%2016)
So we have this equivalent system
![\begin{cases}-x^2+y^2 = 16\\\\x^2-y^2=16\end{cases}](https://tex.z-dn.net/?f=%5Cbegin%7Bcases%7D-x%5E2%2By%5E2%20%3D%2016%5C%5C%5C%5Cx%5E2-y%5E2%3D16%5Cend%7Bcases%7D)
If you add the terms straight down, then you'll find that the x^2 and y^2 terms add to 0. The right hand side terms add to 16+16 = 32
We are left with the equation 0 = 32, which is a false equation or contradiction. Therefore, there are no solutions. We say the system is inconsistent. The two graphs do not intersect at all as shown in the diagram below. We have two hyperbolas in which the branches extend off to infinity to slowly approach the asymptotes. They never actually get to the asymptotes, but only get closer.

Answer:
8
Step-by-step explanation:
we have the expression
![13-0.75w+8x](https://tex.z-dn.net/?f=13-0.75w%2B8x)
For w=12, x=1/2
To evaluate, substitute the value of w and the value of x in the expression
![13-0.75(12)+8(1/2)](https://tex.z-dn.net/?f=13-0.75%2812%29%2B8%281%2F2%29)

Not sure, there is no graph with it. I just edited the question to fix the formatting and to add in info that got cut off when iI pasted it in.
Answer:
tgω= (-0,8)
Step-by-step explanation:
m= ![\frac{-3-5}{6-(-4)} = \frac{-8}{10} =(-0,8)](https://tex.z-dn.net/?f=%5Cfrac%7B-3-5%7D%7B6-%28-4%29%7D%20%3D%20%5Cfrac%7B-8%7D%7B10%7D%20%3D%28-0%2C8%29)
