Option A) Circle.
Step-by-step explanation:
We are given the equation:

A general equation of the circle is of the form:

where (h,k) is the center of the circle and r is the radius of circle.
Comparing the two equations, we get,

Thus, the given equation is equation of a circle centered at (3,12) and of radius 5 units.

Step-by-step explanation:
Answer:
x = 5/2; y = 7
Step-by-step explanation:
2x + y = 12
y = 2x + 2
Use substitution to replace y in the first equation with 2x + 2.
2x + 2x + 2 = 12
4x + 2 = 12
4x = 10
x = 10/4
x = 5/2
y = 2x + 2
y = 2(5/2) + 2 = 5 + 2
y = 7
