Step-by-step explanation:
The formula to find the circumference is
C=d×(3.14)
Therefore you must work backwards to find the radius.
If the circumference is x then divide both sides of the equation by pie to get the diameter. Then once you have the diameter you divide that number by two to get the radius.
Answer:
This system has one solution (-1,1)
Step-by-step explanation:
The attached picture shows the solutions for the system
If we equalize the eq. obtain the following
-x=2x+3
From we obtain that x= -1
Using the first equation y=-x, we obtain that y=1
so (-1,1)
