Answers
(3 , 3) is The harmonic conjugate of (-9,27) with respect to the points (1,7) and (6,-3)
Step-by-step explanation:
The harmonic conjugate of (-9,27) with respect to the points (1,7) and (6,-3)i
First find in which ration (-9 , 27) Divides (1 , 7) & (6 , - 3)
let say m : n ratio
then -9 = ( m*6 + n*1)/(m + n) or -27 = (m *(-3) + n*7)/(m + n)
=> -9m - 9n = 6m + n
=> -15m = 10n
=> m/n = -10/15
=> m/n = - 2/3
=> m:n = - 2: 3
The harmonic conjugate of (-9,27) with respect to the points (1,7) and (6,-3)
will divide point in 2 : 3 ratio
= ( 2*6 + 3*1)/(2 + 3) , (2 *(-3) + 3*7)/(2 + 3)
= 15/5 , 15/5
= 3 , 3

The harmonic conjugate of (-9,27) with respect to the points (1,7) and (6,-3) is (3, 3).
To find : The harmonic conjugate of ( -9, 27 ) with respect to the points ( 1, 7) and ( 6, -3 ) is = ?
Given data :
Let the points a(1, 7) and b(6, -3) and the center p(-9, 27).
= 1 ; = 6 ; = 7 ; = -3
Let a : b be the ratio ⇒ a : b = p
Harmonic conjugate :
-----> (1)
(or)
------> (2)
Taking values of :
6 a + b = -9 ( a + b )
6 a + b = -9 a - 9 b
Arrange the "a" terms and "b" terms like,
6 a + 9 a = -9 b - b
15 a = -10 b
a : b = 2 : 3
Hence, the value of a and b is 2 and 3.
Substituting the value of a and b in the above equation (1) and (2), we get
(1)
(2)
Therefore, the point is (3, 3).
