Answer:
C, E
Step-by-step explanation:
Here, we want to change the equation of a circle from general form to standard form. This is done by making the leading coefficients 1, completing the squares, and then rewriting the equation in standard form.
The leading coefficients of the given equation are 2, so we first want to divide by 2. This gives ...
x² +y² -4x -6y +8 = 0
Subtracting 8 puts us in better position to complete the squares.
x² +y² -4x -6y = -8
Now, we can add the squares of half the coefficients of the linear terms.
(x² -4x +4) +(y² -6x +9) = -8 +13 . . . . . . matches C
And we can simplify this to the standard form equation:
(x -2)² +(y -3)² = 5 . . . . . matches E
the answer is b. I'm pretty sure at least because the square root it roughly 5.91 and that's between 5 and 6.

Answer:
The Correct answer is:
A. You aren’t telling me anything I don’t already know.
Step-by-step explanation:
97.45 / 5 = 19.49 per gallon
and then there is 21.95 per gallon
the better deal would be the 5 gallon bucket for 97.45 because if u buy it this way, it is cheaper by the gallon
