if x varies inversely as y then xy is a constant (k)
eg if x doubles as y halves then examples are:
x = 6, y = any then k = 6y
when x = 12, y = any/2 then k = 12/2 times any ie 6y.
The equation is xy = 22.5
The equation is xy = k where k is the constant of variation. It can also be expressed y = k over x where k is the constant of variation.
Two variables, x and y are in inverse variation if x*y = c for some constant c. The equation can be written in the form y = c/x.
If y varies with x, then there cannot be an inverse variation between x and y!
The inverse variation is the indirect relationship between two variables. The form of the inverse variation is xy = k where k is any real constant.
The equation is xy = 22.5
No. This is not true. It is false. The equation is an example of direct variation.
Two variables, X and Y are said to be in inverse variation if XY = k or Y = k/X for some constant k.
The equation is xy = k where k is the constant of variation. It can also be expressed y = k over x where k is the constant of variation.
Two variables, x and y are in inverse variation if x*y = c for some constant c. The equation can be written in the form y = c/x.
variation
If y varies with x, then there cannot be an inverse variation between x and y!
y = k/x of xy = k where k is a constant.
The equation ( x = \frac{3}{y} ) represents an inverse variation. In inverse variation, as one variable increases, the other decreases, which is evident here since ( y ) is in the denominator. This means that if ( y ) increases, ( x ) decreases, and vice versa.
The inverse variation is the indirect relationship between two variables. The form of the inverse variation is xy = k where k is any real constant.
If a variable X is in inverse variation with a variable Y, then it is in direct variation with the variable (1/Y).
The equation is xy = 5*9 = 45 Alternatively, y = 45/x
