Laura bought 8 3/10 yd of ribbon. she used 1 2/5 yd to tie a package and 2 1/3 yd to make a bow. joe later gave her 4 3/5. how much ribbon does she have now

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

-2x + 7 = 7

subtract 7 from both sides.

-2x = 0

divide both sides by -2.

x = 0
