Answer:
option B
Given : |x + 4| < 5
A. –5 > x + 4 < 5
B. –5 < x + 4 < 5
C. x + 4 < 5 and x + 4 < –5
D. x + 4 < 5 or x + 4 < –5
In general , |x|< n where n is positive
Then we translate to -n < x < n
|x + 4| < 5
5 is positive, so we translate the given absolute inequality to
-5 < x+4 < 5
So option B is correct
A
Divide 400 by the answer the one that shows you a answer is the correct one
Answer: Point B
Reason:
This point is the highest point in the neighborhood or interval. Yes point D is higher up, but points immediately adjacent to point D are higher. This means D is not a relative max. We need a hill shape like where B is located. In contrast, point C is a relative minimum since it is at the bottom of the valley.
Answer:
The coefficient of x is 8
Step-by-step explanation:
Given
--- Perimeter
Required
Determine the coefficient of x
![P = 2(x+8) + 2(3x)](https://tex.z-dn.net/?f=P%20%3D%202%28x%2B8%29%20%2B%202%283x%29)
Open bracket
![P = 2x + 16 + 6x](https://tex.z-dn.net/?f=P%20%3D%202x%20%2B%2016%20%2B%206x)
Collect like terms
![P = 2x + 6x+ 16](https://tex.z-dn.net/?f=P%20%3D%202x%20%2B%206x%2B%2016)
![P = 8x+ 16](https://tex.z-dn.net/?f=P%20%3D%208x%2B%2016)
<em>The coefficient of x is 8</em>
Your answer would be 176.26%
