Answer:
x can be anything. (Infinite solutions)
Step-by-step explanation:
![3\left(x-3\right)+18=3\left(x+3\right)](https://tex.z-dn.net/?f=3%5Cleft%28x-3%5Cright%29%2B18%3D3%5Cleft%28x%2B3%5Cright%29)
Expand:
![3x-3*3+18=3x+3*3](https://tex.z-dn.net/?f=3x-3%2A3%2B18%3D3x%2B3%2A3)
![3x+9=3x+9](https://tex.z-dn.net/?f=3x%2B9%3D3x%2B9)
Subtract 9 from each side:
![3x=3x](https://tex.z-dn.net/?f=3x%3D3x)
Subtract 3x from both sides:
![0=0](https://tex.z-dn.net/?f=0%3D0)
Both sides are equal, and hence this equation is true for any "x" value.
The answer is c have a good day
Answer:
<h3><u>y = - 5x - 10</u></h3>
Step-by-step explanation:
5x + y = - 10
(-5x -5x ) Minus (5x) from both sides
<u><em>y = - 5x - 10</em></u>
Do you have a graphing calculator, or have access to an online one? If so, you just have to put in the expression y = 500,000(0.93)^x. From there, you look where the line would have a y value of near 300,000. Then you see which x value that lies on.
