Coordinates of the center: ( 4, 4 )
The radius: r = 7 - 4 = 3
The equation of a circle:
( x - 4 )² + ( y - 4 )² = 3²
x² - 8 x + 16 + y² - 8 y + 16 = 9
x² + y² - 8 x - 8 y + 32 - 9 = 0
Answer:
A ) x² + y² - 8 x - 8 y + 23 = 0

a is negative and it's not a digit.
<h3>Conclusion: Such a number does not exist.</h3>
Answer:
1.5
Step-by-step explanation:
Given the pair of points on the table.
Now the formula for slope, 
To calculate the slope we only require two pair of points.
Let us take: 

The slope of the linear function represented by the values in the table is 1.5.
Note: You can use any two set of values. The result will be the same.
Answer:
I can not give an exact answer seeing that I do not have access to that assignment but here is what I have. :)
Step-by-step explanation:
Seeing that the angle between "V" and "R" is a 90 degree angle, I can use that to determine the answer for the angle of F,P,V. It is too high for a 45 degree angle and too short for an 80. I then noticed that R,P,Q is about a 40 degree and since there is a 90 degree angle at V,P,R, I can use that and say F,P,V is about a 60-75 degree angle. Hope this helped! :D
