Answer:
(x-1)^2 + y^2 = 25
Step-by-step explanation:
center C ( ( xA + xB)/2 , (yA+yB)/2 ) = ( 1 , 0)
AB = 10
radius = AB / 2 = 5
equation formula: (x - xC)^2 + (y-yC)^2 = radius^2
Hence:
(x-1)^2 + y^2 = 25
The value of x is 2. because you rule out y so it is 6times2is 12+3. that is 15
13x - 6y = 2......multiply by 2
3x - 4y = -10....multiply by -3
------------------
26x - 12y = 4 (result of multiplying by 2)
-9x + 12y = 30 (result of multiplying by -3)
-----------------add
17x = 34
x = 34/17
x = 2
now sub 2 in for x into either of the original equations to find y
3x - 4y = -10
3(2) - 4y = -10
6 - 4y = -10
6 + 10 = 4y
16 = 4y
16/4 = y
4 = y
solution is (2,4)
will rain + will not rain = 100%
72% + will not rain = 100%
will not rain = 28% <em>subtracted 72% from both sides</em>
Answer: 28%
1. True.
2. False. Inert gases are already stable. So, they are is no need for them to be electronegative towards other ions.
3. True. The more electronegative an electron is, it is easier for it to attract the electron from other atoms.
