If y varies directly as x, and y is 48 when x is 6, which expression can be used to find the value of y when x is 2? y = StartFraction 48 Over 6 EndFraction (2)

The expression that can be used to find the value of when is 2 is

()

Step-by-step explanation:

As we know that varies directly as . The following expression is done:

Where is the proportionality constant.

If we know that and , the proportionality constant is:

The expression that can be used to find the value of when is 2 is

answer: evaluate the objective function at each vertex to determine which - and -values, if any, maximize or minimize the function. example: find the minimum value and maximum value of the objective function f ( x , y ) = 4 x + 5 y , subject to the following constraints
