Answer: 
Step-by-step explanation:
x^2+y^2=r^2 --> subtract x^2 to other side
y^2=r^2-x^2 --> square root both sides
y=sqrt(r^2-x^2)
Answer:
Approximately 7.9 feet.
Step-by-step explanation:
cos 10 = x / 8 where x is the required distance.
x = 8 cos 10

Answer:
2/10 7/10
Step-by-step explanation:
Answer:move -5x to the right becomes 5x
Y=5X+2
When x =1 5(1)+2= 7 for Y
When X=2 5(2)+2= 12 for Y
When X =-1 5[-1)+2/ -3
Coordinates (1,7).(2,12)(-1,-3)
