Step-by-step explanation:
To compare two fractions one has to convert them to a common denominator (number underneath the fraction bar). This can be done by finding the LCM (least common multiple) of the two denominators, and then multiplying the numerator and denominator of each respective fraction such that the fraction's denominators are the same. Now all one has to do is compare the numerators, the numerator with a greater value indicates that the fraction is larger.

Step-by-step explanation:
the equation of a circle in standard form is
(x - h)² + (y - k )² = r²
where (h, k ) are the coordinates of the centre and r is the radius
given
x² + y² - 8x + 8y + 23 = 0
collect the x and y terms together and subtract 23 from both sides
x² - 8x + y² + 8y = - 23
using the method of completing the square
add ( half the coefficient of the x / y terms )² to both sides
x² + 2(- 4)x + 16 + y² + 2(4)y + 16 = - 23 + 16 + 16
(x - 4)² + (y + 4)² = 9 ← in standard form
with centre = (4, - 4 ) and r = = 3
