X - Y = 5
- Y = - X + 5
Y = X - 5
==========Now it is a function because it passes the vertical line test.
yes. it is a function

Equations: 3x-5y = 16 and xy = 7 Solutions: (7, 1) and (-5/3, -21/5)
If ( x = 0 ) and ( y = 1 ), then ( xy = 0 \times 1 = 0 ). Therefore, the value of ( xy ) is 0.
mid point of xy
yes. it is a function

Equations: 3x-5y = 16 and xy = 7 Solutions: (7, 1) and (-5/3, -21/5)
If ( x = 0 ) and ( y = 1 ), then ( xy = 0 \times 1 = 0 ). Therefore, the value of ( xy ) is 0.
You cannot have xy= anything. Only x can be there at the end. x=5y=5 Divide 5y for all 3 sides to get 5xy=y Then divide y from both sides to get 5x=1 Therefore, x=1/5
xy = x ÷x y = 1
xy + y = z xy = z - y (xy)/y = (z - y)/y x = (z - y)/y
mid point of xy
That is the commutative property of equality.
The equation is xy = 5*9 = 45 Alternatively, y = 45/x
xy and yx are identical so you have 2xy = 545 ie xy = 272.5. Possible answers 5 and 54.5, 10.9 and 25 etc
To check if the function ( f(xy) ) is continuous on a given interval, you can follow these steps: First, identify the points in the interval where ( xy ) is evaluated. Then, determine if ( f ) itself is continuous at those points by checking if the limit of ( f(xy) ) as ( (x,y) ) approaches any point in the interval equals ( f ) at that point. If both the function and the limit are defined and equal at all points in the interval, then ( f(xy) ) is continuous on that interval.
