Answer:
9
Step-by-step explanation:
3y = 27x
We want to find k when y = kx
Divide each side by 3
3y/3 = 27x/3
y = 9x
The constant of proportionality is 9
Answer:
![{f}^{ - 1} (x) = 9x + 18](https://tex.z-dn.net/?f=%20%7Bf%7D%5E%7B%20-%201%7D%20%28x%29%20%3D%209x%20%2B%2018)
Step-by-step explanation:
![f(x) = \frac{1}{9}x - 2](https://tex.z-dn.net/?f=f%28x%29%20%3D%20%20%5Cfrac%7B1%7D%7B9%7Dx%20-%202)
![y = \frac{1}{9} x - 2](https://tex.z-dn.net/?f=y%20%3D%20%5Cfrac%7B1%7D%7B9%7D%20x%20-%202)
![x = \frac{1}{9}y - 2](https://tex.z-dn.net/?f=x%20%3D%20%20%5Cfrac%7B1%7D%7B9%7Dy%20-%202)
![x + 2 = \frac{1}{9}y](https://tex.z-dn.net/?f=x%20%2B%202%20%3D%20%20%5Cfrac%7B1%7D%7B9%7Dy)
![9x + 18 = y](https://tex.z-dn.net/?f=9x%20%2B%2018%20%3D%20y)
![{f}^{ - 1} (x) = 9x + 18](https://tex.z-dn.net/?f=%20%7Bf%7D%5E%7B%20-%201%7D%20%28x%29%20%3D%209x%20%2B%2018)
Answer:
The answer is the letter B.
The first column represents the x-values, and the second row represents the y-values.
For that reason, if we have:
2x - 7y = -1
x + 3y = -5
Then, the matrix will be given by:
[ 2 -7
1 3]
Then, the third colum will be the equality:
[ -1
-5]
So the correct option is the letter B.
54 x 1
2 x 27
3x 18
4 x 14
6 x 9
Cone and cylinder both have round bases
