They are growing at the same rate
First, get one of the variables on its own. I'm going to do the first equation since it looks easier. :)
![3x + 6y = 18](https://tex.z-dn.net/?f=3x%20%20%2B%206y%20%3D%2018)
Subtract 6y from both sides.
![3x = 18 - 6y](https://tex.z-dn.net/?f=3x%20%3D%2018%20-%206y)
Divide both sides by 3 to get the variable alone.
![x = 6 - 2y](https://tex.z-dn.net/?f=x%20%3D%206%20-%202y)
Plug this into the other equation for x.
![3y = - \frac{3}{2} (6 - 2y) + 9](https://tex.z-dn.net/?f=3y%20%3D%20%20-%20%20%5Cfrac%7B3%7D%7B2%7D%20%286%20-%202y%29%20%2B%209)
Distribute.
![3y = - 9 + 3y + 9](https://tex.z-dn.net/?f=3y%20%3D%20%20-%209%20%2B%203y%20%2B%209)
Add like terms.
![3y = 3y](https://tex.z-dn.net/?f=3y%20%3D%203y)
The system has infinitely many solutions because both sides equal each other.
Hope this helped!

Answer
4(y - 6)
Explanation
The difference of y and 6 can mathematically be represented as y - 6.
Therefore, four times the difference of y and six will be 4(y - 6).
Answer:
PT, VP
Step-by-step explanation:
if p is the center and T V and W are on the circle
the radius goes from the center of the circle to the edge of the circle
then PW PT and PW are radii of the circle
