Answer:
its A
Step-by-step explanation:
Ans given below
-3r-12=-21
-3r=-21+12
-3r=-9
r=-9\-3
r=3
Step-by-step explanation:
it is option c. you interchange the value with y and take inverse.
The standard equation of a circle is given by:
(x-a)²+(y-b)²=r²
where:
(a,b) is the center and r is the radius.
Given that (a,b) is (-8,-3) and r=2 units
then the equation of the circle will be:
(x-(-8))²+(y-(-3))²=2²
simplifying the above we get:
(x+8)²+(y+3)²=4
