The variables x and y are proportional. Use the values to find the constant of proportionality. Then write an equation that relates x and y . When y=72 , x=3 .

Answer:

equation: y = 24x

Step-by-step explanation:

if y and x is proportional,

y = kx

72 = k * 3

k = 24

→ Here the constant if 24

so the equation that relates x and y :

y = 24x

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
