(40)/(12)+(2)/(x-y)=5,(25)/(x+y)-(3)/(x-y)=1

Subtract : (3)/(2)x^(2)y+(4)/(5)y-(1)/(3)x^(2)yz from (12)/(5)x^(2)yz-(3)/(5)xyz+(2)/(3)x^(2)y

7(x-2y)^2-25(x-2y)+12

7(x-2y)^(2)-25(x-2y)+12

Find the products: (3/x-5/y)(9/(x^2)+(25)/(y^2)+(15)/(x y))

If (x)/(4) + ( y)/(3) = (5)/(12) and (x)/(2) + y = 1 then find the value of (x + y ) .

Draw the graph of each of the following : (i)(x)/(3)+(y)/(5)=1 , (ii) (2x+6)/(5)=y-1 , (iii) 3x+4y=12 , (iv)3x-y=2

For hyperbola whose center is at (1, 2) and the asymptotes are parallel to lines 2x+3y=0 and x+2y=1 , the equation of the hyperbola passing through (2, 4) is (a) (2x+3y-5)(x+2y-8)=40 (b) (2x+3y-8)(x+2y-5)=40 (c) (2x+3y-8)(x+2y-5)=30 (d) none of these
