Which of these statements are true for joint variations? Check all that apply.
There are at least two constants of
proportionality
The independent variable is related to the
product of the independent variables by a
constant of proportionality, k.
The equation must have at least two
independent variables.
The constant of proportionality is 1.

none of the above.

for one of the equations to be used in the process, there has to be a term in the equation since squared is .

since there is only a term in the first equation, we cannot derive a from completing the square.

solving with completing the square
