Answer:
When x=8, y=-6. When x=10, y=0
Step-by-step explanation:
![y=3x-30\\x^2+y^2=100](https://tex.z-dn.net/?f=y%3D3x-30%5C%5Cx%5E2%2By%5E2%3D100)
You can plug the given y value into the second equation to get:
![x^2+(3x-30)^2=100\\x^2+9x^2-180x+900=100\\10x^2-180x+800=0\\10(x^2-18x+80)=0\\10(x-8)(x+10)=0\\x= 8, 10\\y= -6, 0](https://tex.z-dn.net/?f=x%5E2%2B%283x-30%29%5E2%3D100%5C%5Cx%5E2%2B9x%5E2-180x%2B900%3D100%5C%5C10x%5E2-180x%2B800%3D0%5C%5C10%28x%5E2-18x%2B80%29%3D0%5C%5C10%28x-8%29%28x%2B10%29%3D0%5C%5Cx%3D%208%2C%2010%5C%5Cy%3D%20-6%2C%200)
Hope this helps!
