This is the same as saying x*y+25=0.

Also, x*y=-25.

The solution (if you had to find it) would be -5 and 5.

To graph, it would be y=-25/x

Edit: This can be simplified down to y=-5 since it is a constant so it would be a straight line on the y-axis down at -5.

notsponge [240]

Answer:

2/3 or 3/2

Step-by-step explanation:

Let x represent the number. The given relation is ...

x +1/x = 2 1/6

x^2 +1 = (13/6)x

6x^2 -13x +6 = 0 . . . . . subtract the right side and multiply by 6

(6x -9)(6x -4)/6 = 0 . . . . factor

(2x -3)(3x -2) = 0 . . . . . . simplify a bit

x = 3/2 or 2/3 . . . . . . . . values of x that make the factors zero

The number is 2/3 or its reciprocal, 3/2.
