Answer:
The equation of a circle:
Step-by-step explanation:
The equation of a circle:
(where the center is known as and the radius, known as
).
-Since you already have the center and the radius, use them for the equation of a circle:
Center:
Radius:
After you have the equation of a circle, simplify the radius by the exponent :
So, you have found the equation of a circle.
Answer:
This system of equations has no solution.
Step-by-step explanation:
Solving a system of equations can be done using a few different methods. Since your second equation is already solved for 'y', you can substitute this expression (-x + 3) for the value of 'y' in the first equation:
2x + 4(-x + 3) = 10
Distribute: 2x - 2x + 12 = 10
Combine like terms: 0 + 12 = 10 or 12 ≠ 10
Since the variables cancel out and 12 ≠ 10, there are no solutions to this system.
