Answer:
(x-2)²+(y+3)²=9
Step-by-step explanation:
We know that the formula for the area of the circle is:
(x-h)²+(y-k)²=r²
-h,k being the center coordinates
-r being the radius
In this case, (2,-3) are the center coordinates and 3 the radius, so simply plug these into the equation giving us:
(x-2)²+(y+3)²=9
Answer:
17 more
Step-by-step explanation:
68-25%= 51.........
sqrt(36/100) = +-6/10
You find the square root of the numerator and the denominator.
If you use the first answer, the equation becomes 2x + 2y = 16. You could subtract this from equation Q to eliminate x.
The second answer makes equation P -2x - 2y = -16. You could add this to equation Q to eliminate x. You can use both of these methods to eliminate the x term, but if you can only choose one, you should choose the second option.
