Please help I don’t know the answer :(
gogolik [260]

Answer:

When x=8, y=-6. When x=10, y=0

Step-by-step explanation:

y=3x-30\\x^2+y^2=100

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

Hope this helps!
