Completing the square:
x^2 - 18x + y^2 + 8y = -5
x^2-18x +81 - 81 + y^2 + 8y + 16 - 16 = -5.
Then, (x-9)^2 + (y+4)^2 = -5 + 81 + 16 = 92
Then the desired equation is (x-9)^2 + (y+4)^2 = 92.

Answer:
5/7
Step-by-step explanation:
You find a slope by using the equation y2-y1/x2-x1.
In this case: 15-5/21-7
10/14
5/7
We can model the trip of the clock hand as shown in the picture below:
The clock hand is of the same length, '

' and it forms a right-angle triangle from 1:15 to 1:30
We can use the Pythagoras theorem to find the length of the minute hand





Answer : 10.6 (to the nearest tenth)
