Answer:
(x+9)^2+(y+6)^2=36
Step-by-step explanation:
The equation of a circle is (x-h)^2+(y-k)^2=r^2 where (h,k) is the given center and r is the radius of the circle.
Given a center of (-9,-6) we have (x+9)^2+(y+6)^2=r^2 so far.
Since the diameter is 12, half of that is the radius which is 6, so the equation of the circle is (x+9)^2+(y+6)^2=36 (as 36 is 6^2)
Answer:
x = -8
Step-by-step explanation:
- 7x+23 = 4x-1
- 3x + 23 = -1
- 3x = -24
- x = -8
Answer:
-x+2
Step-by-step explanation:
3x+(2−4x)
=3x+2-4x
=3x-4x+2
=-x+2
I hope this helps!
Answer:
34°
Step-by-step explanation:
The measure of vertical angles formed by two chords is equal to one half the sum the measures of the arcs.
In other words, x is the average:
x = (23° + 45°) / 2
x = 34°
