Mrs. Culland is finding the center of a circle whose equation is x2 + y2 + 6x + 4y – 3 = 0 by completing the square. Her work is
andrew11 [14]

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:

x^2+y^2+6x+4y-3 = 0

In order to complete the square the terms have to be combined first

x^2+y^2+6x+4y = 3\\x^2+6x+y^2+4y=3\\(x^2+6x)+(y^2+4y) = 3

9 and 4 will be added to both sides of the equation to complete the square

(x^2+6x+9)+(y^2+4y+4) = 3+9+4\\(x^2+6x+9)+(y^2+4y+4) = 16

The next step completes the work

(x+3)^2+(y+2)^2 = (4)^2\\

Comparing with the standard form of circle

(x-h)^2 + (y-k)^2 = r^2\\x - h = x+3\\h=-3\\y-k = y+2\\k = -2

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)

Answer: T

=

$

Step-by-step explanation: Hmm...

Let's organize this problem.

Since he saved

$

30

, he as

$

30

Now, that is five-sixths of the total cost of the game.

Let's name the total cost

T

.

If we have a fraction of something, say, half of four, we multiply the fraction by the whole.

half of four

1

2

⋅

4

Similarly, two-thirds of the total can be represented as:

5

6

⋅

T

Now, the problem is telling us that

$

30

is equal to the expression above.

Therefore,

2/3

T

=

30

=>

6

5

T

=
