Answer:
Third option:
and ![x = 2](https://tex.z-dn.net/?f=x%20%3D%202)
Step-by-step explanation:
Given:
![|-2x|=4](https://tex.z-dn.net/?f=%7C-2x%7C%3D4)
For a modulus function, if
, then,
![f(x)=\pm a](https://tex.z-dn.net/?f=f%28x%29%3D%5Cpm%20a)
Here,
, ![a=4](https://tex.z-dn.net/?f=a%3D4)
∴ ![-2x=\pm 4\\ -2x=-4\textrm{ or } -2x=4\\ x=\frac{-4}{-2}\textrm{ or }x=\frac{4}{-2}\\ x= 2\textrm{ or }x=-2](https://tex.z-dn.net/?f=-2x%3D%5Cpm%204%5C%5C%20-2x%3D-4%5Ctextrm%7B%20or%20%7D%20-2x%3D4%5C%5C%20x%3D%5Cfrac%7B-4%7D%7B-2%7D%5Ctextrm%7B%20or%20%7Dx%3D%5Cfrac%7B4%7D%7B-2%7D%5C%5C%20x%3D%202%5Ctextrm%7B%20or%20%7Dx%3D-2)
Therefore, the third option is the correct answer as the graph has
values as -2 and 2
Answer:
D. -3.3
Step-by-step explanation:
=> 2.8x = -9.24
=> x = -9.24/2.8
=> x = -3.3
Answer:
A) n^2-4n+16 = (n-4)^2 +4n
= (n-2)(n-8)+6n = (n-16)(n-1) +13n
Or it's already in factored form
