Answer:
Step-by-step explanation:
The general equation of the circle is:
(x-h)²+(y-k)²=r²
(h, k)=(-3,-5) are the coordinates of the center of the circle.
r=6 is the radius
The equation of the circle is:
(x+3)²+(y+5)² = 36
Answer:
The first one
because 8 - 3 = 5 and is not less than it
hope this helps :)

Answer:
68°F is 20°C
Step-by-step explanation:
C = (5/9)(F - 32)
C = (5/9)(68 - 32)
C = (5/9)(36)
C = 5 * 4
C = 20
Answer: 68°F is 20°C
Answer:
5.5, 9.5
Step-by-step explanation:
Let x and y be the numbers
x+y = 15
x-y = 4
Add the two equations together to eliminate y
x+y = 15
x-y = 4
------------------
2x = 19
Divide by 2
2x/2 =19/2
x = 9.5
Now find y
x+y = 15
9.5+y = 15
Subtract 9.5
x = 15-9.5
x =5.5
