Answer:
Explanation:
We must write this equation in the form
(
x
−
a
)
2
+
(
y
−
b
)
2
=
r
2
Where
(
a
,
b
)
are the co ordinates of the center of the circle and the radius is
r
.
So the equation is
x
2
+
y
2
−
10
x
+
6
y
+
18
=
0
Complete the squares so add 25 on both sides of the equation
x
2
+
y
2
−
10
x
+
25
+
6
y
+
18
=
0
+
25
=
(
x
−
5
)
2
+
y
2
+
6
y
+
18
=
0
+
25
Now add 9 on both sides
(
x
−
5
)
2
+
y
2
+
6
y
+
18
+
9
=
0
+
25
+
9
=
(
x
−
5
)
2
+
(
y
+
3
)
2
+
18
=
0
+
25
+
9
This becomes
(
x
−
5
)
2
+
(
y
+
3
)
2
=
16
So we can see that the centre is
(
5
,
−
3
)
and the radius is
√
16
or 4
Answer:
m=2/3
Step-by-step explanation:
your answer would be A.
Answer:
its a estamite just guess
Step-by-step explanation:
Answer:
a. 0
Step-by-step explanation:
1. To find the slope given two points, use the following formula:
2. 
would be the second y-value (in the second ordered pair), 2, and 
would be the first y-value (in the first ordered pair), also 2.
3. Same for the x-values. 
is -2 and 
is 4
4. Now plug in the values.
5. This equals 
which simplifies to 0
Let 
.
Simplifying both you get 
.
The set conjunction is 
.
So the answer is B.
Hope this helps.
