If x varies inversely with y when x=6 , y =8 then x =8 , y=____

If x and y vary inversely and x =5 when y = (2)/(3) then for x = 10 , y = ___

Let y vary directly as x. if y=12 when x=4, then write a linear equation, what is the value of y when x=5?

Statement -1 If x,y,z be real variables satisfying x+y+z=6 and xy+yz+z=8 , the range of variables x,y and z are identical. Statement -2 x+y+z=6 and xy+yz+zx=8 remains same if x,y,z interchange their positions.

What are the coefficients of x in the following expressions? 4x – 3y, 8 – x + y, y^2x – y, 2z – 5xz

In each of the following x and y vary directly with each other . Find the constant of variable . (i) y = 3x (ii) 2x=3y (iii) 9x=y (iv) y = 2x

The area bounded by the curve y^(2) = 8x and x^(2) = 8y is :

Solve the following linear programming problem graphically. Maximize the objective function Z = 8x + 9y subject to the constraints x + y le 6, x + 2y le 8, x ge 2, x ge 0, y ge 0 .
