The generic equation of the circle is given by:

Where,
r: radius of the circle
(xo, yo): center of the circle.
The center of the circle in this case is:

The radius of the circle is:

Substituting values we have:

Rewriting the equation we have:
Answer:
The general form of the equation of a circle with center at (a, b) and radius of length m is:
option A
Answer:
x^2 + 2x + 3
Step-by-step explanation:
x^2 - 2x -2 + (4x +5) -------------> x^2 +2x +3
In terms of x so it stays the same
Answer:
4.5
Step-by-step explanation:
8/6= 6/y
Cross multiply:
8(y) = 6(6)
8y = 36
Divide both sides by 8:
8y/8 = 36/8
y = 4.5
Answer:
<em>RQ = 9 units</em>
Step-by-step explanation:
The answer
please look at the image on the attached file
when all the inequalities are placed, the result figure is a triangle
so the answer is a triangle
its area can be determined by the following formula:
S= w x l
according to the figure w = 6, and l=10
so S = 6x10=60 cm²
