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:

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

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

The next step completes the work

Comparing with the standard form of circle

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)

18 t - 18 t * 30% = 18 t - 17 * 0,3 = 18 t - 5,4 t = 12,6 t
Answer:
$8.5 per hour
Step-by-step explanation:
Number of overtime hours = 4 hours
Since overtime starts after 40 hours, then the number of hours worked = 40 + 4 = 44 hours
Total amount earned = $391
Let Hourly pay = x
Overtime pay = 1 1/2x = 3/2x
Therefore ;
40x + (4*3/2x) = 391
40x + 6x = 391
46x = 391
x = 391 / 46
x = 8.5
Hourly pay = $8.5 per hour
