Answer:
Step-by-step explanation:
x² + 2x - 3 + y² = 5
Strategy:
Convert the equation to the centre-radius form:
(x - h)² + (y - k)² = r²
The centre of the circle is at (h, k) and the radius is r
.
Solution:
Move the number to the right-hand side.
x² + 2x + y² = 8
Complete the square for x
(Take half the coefficient of x, square it, and add to each side of the equation)
(x² + 2x + 1) + y² = 9
Complete the square for y
The coefficient of y is zero.
(x² + 2x + 1) + y² = 9
Express the result as the sum of squares
(x + 1)² + y² = 3²
h = -1; k = 0; r = 3
The centre of the circle is at 
The graph of the circle below has its centre at (-1,0) and radius 3.

Credit card balance each month:
First month: 1020 .00
Second month: 1040.4 0
Third month: 1061,208
Fourth month: 1082.43
Here we have to calculate the interest and add it to capital.
That is, 2% of 1000
First month:
Interest = 1000 (2/100)
Odds1 = 1020
Second month
Capital 1020
Interest = 1020 x 0.02 = 20.4
Odds2 = 1040.4
Third month
Capital = 1040.4
Interest = 1040.4 x 0.02 = 20.808
Odds3 = 1061,208
Fourth month
Capital = 1061,208
Interest = 1061.208 x 0.02 = 21.22
Odds = 1082.43
Therefore the credit card balance each month:
First month: 1020 .00
Second month: 1040.4 0
Third month: 1061,208
Fourth month: 1082.43
