If y varies directly and y is 12 when x is 1.2 what is the constant of variation for this relation

10

Step-by-step explanation:

The constant of variation would be 12 / 1.2 = 10.

Step-by-step explanation:

The constant of variation 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
