Answer:
![XY = 2](https://tex.z-dn.net/?f=XY%20%3D%202)
![ZW = 2](https://tex.z-dn.net/?f=ZW%20%3D%202)
XY and ZW are congruent
Step-by-step explanation:
Given
![X = -7](https://tex.z-dn.net/?f=X%20%3D%20-7)
![Y = -5](https://tex.z-dn.net/?f=Y%20%3D%20-5)
![Z = 2](https://tex.z-dn.net/?f=Z%20%3D%202)
![W = 4](https://tex.z-dn.net/?f=W%20%3D%204)
Distance XY is calculated as thus:
![XY = |X - Y|](https://tex.z-dn.net/?f=XY%20%3D%20%7CX%20-%20Y%7C)
![XY = |-7 - (-5)|](https://tex.z-dn.net/?f=XY%20%3D%20%7C-7%20-%20%28-5%29%7C)
![XY = |-7 + 5|](https://tex.z-dn.net/?f=XY%20%3D%20%7C-7%20%2B%205%7C)
![XY = |-2|](https://tex.z-dn.net/?f=XY%20%3D%20%7C-2%7C)
![XY = 2](https://tex.z-dn.net/?f=XY%20%3D%202)
Distance ZW is calculated as thus:
![ZW = |Z - W|](https://tex.z-dn.net/?f=ZW%20%3D%20%7CZ%20-%20W%7C)
![ZW = |2 - 4|](https://tex.z-dn.net/?f=ZW%20%3D%20%7C2%20-%204%7C)
![ZW = |-2|](https://tex.z-dn.net/?f=ZW%20%3D%20%7C-2%7C)
![ZW = 2](https://tex.z-dn.net/?f=ZW%20%3D%202)
![XY = ZW = 2](https://tex.z-dn.net/?f=XY%20%3D%20ZW%20%3D%202)
<em>Hence:</em>
<em>XY and ZW are congruent</em>
Permeability, this is how fast or slow the soil can absorb the water.
The slope of the lined graph is 5/4
Answer:
20 paitents
Step-by-step explanation:
In the word problem since x represents the number of hours all you have to do is plug in 5 for the x-value.
y = 4 (5)
once you do that, multiply 4 x 5 and you get 20.
Answer:
14x-85
Step-by-step explanation:
The area of the shaded region is
![(x + 6)(x - 6) - {(x - 7)}^{2}](https://tex.z-dn.net/?f=%28x%20%2B%206%29%28x%20-%206%29%20-%20%20%7B%28x%20-%207%29%7D%5E%7B2%7D%20)
which if you use the identities to expand it gives you
![{x}^{2} - 36 - {x}^{2} + 14x - 49](https://tex.z-dn.net/?f=%20%7Bx%7D%5E%7B2%7D%20%20-%2036%20-%20%20%7Bx%7D%5E%7B2%7D%20%20%2B%2014x%20-%2049)
This then reduces to be
![14x - 85](https://tex.z-dn.net/?f=14x%20-%2085)
