Answer:

Total Number of lines will be 28

Step-by-step explanation:

We can use combinations to solve this question.

Let the two Collinear points be denoted by A and B and the other other points be denoted by x1,x2,x3,x4, x5 and x6.

Suppose that only A and B are collinear.

The number of lines determined by any two of x1 to x6  are given by 6C2= 15

The number of lines from A or B and x1---x6 is given by 6C1 * 2C1= 12

The number of lines from A to B is 1.

Total Number of lines = 15+ 12+ 1= 28

Obtain the general solution of<br> y ln x ln y dx + dy = 0
oksano4ka [1.4K]
Dy/dx = -y inx iny

(y in x in y) dx + dy = 0

(y in x in y ) dx = - dy

(in x )dx =  - (1/ y in y) dy

you just need to integrate both sides

Hope this helps

one positive number is 28 less than another number. if the reciprocal of the smaller number is added to four times the reciproca
marishachu [46]
Let x represent the larger number.
  1/(x -28) +4/x = 1/6
Multiplying by the product of denominators, we have
  6x +24(x -28) = x(x -28)
In standard form, this is
  x^2 -58x +672 = 0
  (x -42)(x -16) = 0

The two numbers are (-12 and 16) or (14 and 42).
