Solve [3-4 9 2][x y]=[10 2] for x\ a n d\ y .

I. x^(2) - 10x+24 = 0 II. y^(2) - 9y + 20 = 0

The minimum value of the expression 3x + 2y (AA x, y >0) , where xy^(2) = 10 , occurs when the value of y is equal to

2x^(2) - 9x+10 = 0 y^(2) - 18y+72 = 0

4x + (10) / (y) = 2; 9x- (4) / (y) = (17) / (20)

Image of circle C:x^(2)+y^(2)-8x-10y+16=0 are taken in variable line (lambda+1)x+(1-2 lambda)y+lambda=2AA lambda in R If locus of centre of there image intersects circle ^ prime C' at A and B, then (AB)/(sqrt(3)), is

( 10 )/( x+ y) + (2 ) /(x - y ) = 4 , ( 15)/( x + y ) - (9) /( x - y) = - 2 .

Verify the property x + y = y + x of rational numbers by taking x=(-2)/(5), y= (-9)/(10)
