The center is at (0,0) so the equation will be like
x^2 + y^2 = r^2 where r = radius of the circle.
from the diagram you can see that r = 4
answer is x^2 + y^2 = 16
A mile=5280 feet
1/40 mile*(5280 feet/1 mile)=132 feet
132 feet-------------------1/2 hour
x------------------------------1 hour
x=(132 feet*1 hour) / (1/2 hour)=264 feet/hour.
264 feet/h *(1 mile/5280 feet)=0.05 miles/ h
Solution: S=264 feet/h (≈0.05 miles/h)
The answer to this question is x=54
2x+2=3x-52
2x=3x-54
-x=-54
x=54
I hope this helps!!!!!
Answer:
2
Step-by-step explanation:
3x+2=11
(you need to isolate x, so step 1 is to subtract 2 from both sides.)
3x+2-2=11-2
3x=9
(then divide both sides by 3)
3x/3=9/3
x=3
