Step-by-step explanation:
x2+6x+9-9+y2-4y+4-4=23
(x+3)2-9+(y-2)2-4=23
(x+3)2+(y-2)2=36

Answer:
16
Step-by-step explanation:
45 +25+25+10+10+19=134 so 150-135=16
Answer is A) -1 because it they are parallel then they have the same slope. If the green line has a -1 slope so does the red line
Answer:
-16
Step-by-step explanation:
The average of –25, –70, 15, –31, –25, and 40 is -16
To determine the average of the numbers given, we shall find their sum then divide this sum by the number of values;
The sum of the numbers is;
-25-70+15-31-25+40 = -96
We have a total of 6 values, thus the average becomes;
(-96)/6 = -16
