To find the area of a circle find the radius and square it then multiply by PI
Area = PI x r^2
F(x)=x-3 I think but I am not sure
2-10 = -8 I'm not sure what the 5,6,7,8,9,10 means if you tell me i might be able to help you
You would need to change the slope to -6 because perpendicular lines have opposite reciprocal slopes.
2x-7=43
2x=50
x=25
I hope I helped you with your solution! If you could give me brainliest, I would be very thankful!
