Answer:
4-12x
Step-by-step explanation:
-2/3*-6 is 4
-6*2 is -12
4-12x
Answer:
The correct option is B.
Step-by-step explanation:
The given function is
![f(x)=x](https://tex.z-dn.net/?f=f%28x%29%3Dx)
The new function is
![g(x)=-\frac{1}{2}f(x)](https://tex.z-dn.net/?f=g%28x%29%3D-%5Cfrac%7B1%7D%7B2%7Df%28x%29)
.... (1)
It is in the form of
.... (2)
Where, m is a constant.
If m is negative, then there is a vertical reflection over x-axis. If the constant is greater than 1, we get a vertical stretch and if the constant is between 0 and 1, we get a vertical compression.
From (1) and (2), we get
![m=-\frac{1}{2}](https://tex.z-dn.net/?f=m%3D-%5Cfrac%7B1%7D%7B2%7D)
Since the value of m is negative and absolute value of m is between 0 and 1, therefore the graph g(x) shows the vertical reflection over x-axis and vertical compression.
Option B is correct.

Answer: ![\frac{1}{2}](https://tex.z-dn.net/?f=%5Cfrac%7B1%7D%7B2%7D)
Step-by-step explanation:
Use the formula for calculate the distance between two points:
![d=\sqrt{(x_2-x_1)^2+(y_2-y_1)^2}](https://tex.z-dn.net/?f=d%3D%5Csqrt%7B%28x_2-x_1%29%5E2%2B%28y_2-y_1%29%5E2%7D)
Calculate the distance AB. Substitute the coordinates into the formula. Then:
![d_{AB}=\sqrt{(8-0)^2+(8-(-7))^2}](https://tex.z-dn.net/?f=d_%7BAB%7D%3D%5Csqrt%7B%288-0%29%5E2%2B%288-%28-7%29%29%5E2%7D)
![d_{AB}=17](https://tex.z-dn.net/?f=d_%7BAB%7D%3D17)
Calculate the distance A'B'. Substitute the coordinates into the formula. Then:
![d_{A'B'}=\sqrt{(2-6)^2+(1-5-(-6))^2}](https://tex.z-dn.net/?f=d_%7BA%27B%27%7D%3D%5Csqrt%7B%282-6%29%5E2%2B%281-5-%28-6%29%29%5E2%7D)
![d_{A'B'}=\frac{17}{2}](https://tex.z-dn.net/?f=d_%7BA%27B%27%7D%3D%5Cfrac%7B17%7D%7B2%7D)
As you can see, the distance A'B' is the distance AB multiplied by 1/2. Therefore, this is the scale factor.
