Which point is on the circle described by (x - 2)2 + (y + 3)2 = 4?

a. (2, -5)
b. (2, 0)
c. (0, 0)
d. (1, -4)

 The correct option is (A) (2, -5).

Step-by-step explanation:  We are to select the point that is on the circle described by the following equation :

Option (A) :

(x, y) = (2, -5).

We have

So, the point (2, -5) lies on the circle (i). And so, option (A) is correct.  

Option (B) :

(x, y) = (2, 0).

We have

So, the point (2, 0) lies outside the circle (i). And so, option (B) is incorrect.

Option (C) :

(x, y) = (0, 0).

We have

So, the point (0, 0) lies outside the circle (i). And so, option (C) is incorrect.  

Option (D) :

(x, y) = (1, -4).

We have

So, the point (2, -5) lies inside the circle (i). And so, option (D) is incorrect.  

Thus, (A) is the correct option.

the answer is 0.3175 hope that you ^w^

also you might actually want to put this picture up if you want people to solve it luckily i remember this question

option (b) is correct

step-by-step explanation:

to find the solution of this system, we need to convert it into reduced row-echelon form. we have,

after applying row operations r2 -> r2/2 and r3 -> r3/3, we get,
