Answer:
The system has one solution.
Step-by-step explanation:
To find the number of solutions of the system, we equal both equations for y.
If we have ax = b, in which both a and b are different of 0, we have one solution.
If both a and b are 0, we have infinite solutions.
If a is 0 and b is not, there are no solutions.
y=6/7x-8 and y=7/9x+10/9
So
![\frac{6x}{7} - 8 = \frac{7x}{9} + \frac{10}{9}](https://tex.z-dn.net/?f=%5Cfrac%7B6x%7D%7B7%7D%20-%208%20%3D%20%5Cfrac%7B7x%7D%7B9%7D%20%2B%20%5Cfrac%7B10%7D%7B9%7D)
![\frac{6x}{7} - \frac{7x}{9} = \frac{10}{9} + 8](https://tex.z-dn.net/?f=%5Cfrac%7B6x%7D%7B7%7D%20-%20%5Cfrac%7B7x%7D%7B9%7D%20%3D%20%5Cfrac%7B10%7D%7B9%7D%20%2B%208)
![\frac{54x - 49x}{63} = \frac{10}{9} + \frac{72}{9}](https://tex.z-dn.net/?f=%5Cfrac%7B54x%20-%2049x%7D%7B63%7D%20%3D%20%5Cfrac%7B10%7D%7B9%7D%20%2B%20%5Cfrac%7B72%7D%7B9%7D)
![\frac{5x}{63} = \frac{82}{9}](https://tex.z-dn.net/?f=%5Cfrac%7B5x%7D%7B63%7D%20%3D%20%5Cfrac%7B82%7D%7B9%7D)
![45x = 63*82](https://tex.z-dn.net/?f=45x%20%3D%2063%2A82)
Both a and b are different of 0, so the system has one solution.

Answer:
459
Step-by-step explanation:
because 3^5 is 243 and 6^3 is 216 then add up 243+216=459
Answer:
x=5, y=(5)/2
Step-by-step explanation:
Using the 30-60-90 triangle rule, we know that the sides follow 1-(/2)-2. The ratio between the side and the rule is 5/2, meaning that we know that y=(5)/2 and x=5.
