The correct answer is:
(x + 3)^2 + (y + 2)^2 = 4^2, so the center is (–3, –2)
Further explanation:
The given equation of circle is:
In order to complete the square the terms have to be combined first
9 and 4 will be added to both sides of the equation to complete the square
The next step completes the work
Comparing with the standard form of circle
As the centre is (h,k), the centre of given circle will be:
(-3,-2)
Hence the correct answer is:
(x + 3)^2 + (y + 2)^2 = 4^2, so the center is (–3, –2)

The amount he had to pay if he have to purchase a laptop today that is the same value as the one he saw in the ad is $ 390.24.
Given that:-
Price of the laptop after 1 year = $ 400.
Inflation rate = 2.5 %
We have to find the amount he had to pay if he have to purchase a laptop today that is the same value as the one he saw in the ad.
Let the price he had to pay be x.
Hence, we can write,
x + (x*(2.5)*1)/100 = 400
x(1 + 1/40) = 400
x(41/40) = 400
x = 400*40/41 = $ 16000/41 = $ 390.24.
