Answer:
I would say 16=1.2n+(negative 8) because they are in the same order as it was spelled in words and not numbers that's how I know that it could be 16=1.2n+(negative 8).
Step-by-step explanation:
Answer:
zeroes: x = -9 and x = -7
Step-by-step explanation:
f(x)=(x+8)^2−1
A "zero" refers to when the y-value on the graph is zero.
0 = (x+8)^2 - 1
1 = (x+8)^2
+ or - 1 = x+8
so break them apart into two equations
x+8 = 1 OR x+8 = -1
x = -7 OR x = -9
You can plug both back in to check that the equation works!

Answer:
The scale factor of given coordinate
A is correct.
Step-by-step explanation:
We are given two coordinate O and K. The dilation with respect to origin.
![D_{O,K}(6,12)\rightarrow (3,6)](https://tex.z-dn.net/?f=D_%7BO%2CK%7D%286%2C12%29%5Crightarrow%20%283%2C6%29)
For scale factor,
![(x,y)\rightarrow (ax,ay)](https://tex.z-dn.net/?f=%28x%2Cy%29%5Crightarrow%20%28ax%2Cay%29)
a is scale factor of coordinate.
If we divide new coordinate with old coordinate to get scale factor.
![\text{ scale factor}=\dfrac{\text{x-value of new coordinate }}{\text{x-value of old coordinate}}](https://tex.z-dn.net/?f=%5Ctext%7B%20scale%20factor%7D%3D%5Cdfrac%7B%5Ctext%7Bx-value%20of%20new%20coordinate%20%7D%7D%7B%5Ctext%7Bx-value%20of%20old%20coordinate%7D%7D)
![\text{ scale factor}=\dfrac{3}{6}=\dfrac{1}{2}](https://tex.z-dn.net/?f=%5Ctext%7B%20scale%20factor%7D%3D%5Cdfrac%7B3%7D%7B6%7D%3D%5Cdfrac%7B1%7D%7B2%7D)
Hence, The scale factor of given coordinate
