Find the maximum and minimum values of the objective function f(x, y) and for what values of x and y they occur, subject to the given constraints.
f(x, y) = 2x + 6y
x ≥ 0
y ≥ 0
2x + 7y ≤ 70
8x + 4y ≤ 136

a. max at (14,6)=64, min at (0,0)=0
b. max at (15,9)= 84, min at (0,0)=0
c. max at (0,10)=60, min at (0,0)=0
d. max at (17,0)=34, min at (0,0)=0

C. is not the answer

i = 2 / - 5

step-by-step explanation:

evaluation of ( 2 - 4 ) ( p + q ) when p = 2 and q = 5 i, by putting values of p and q,

step-by-step explanation:

step-by-step explanation:

points a and b are equidistant from the desired line, so the line you find by using them will go through point r.

using points other than a and b will give the desired line only if they are equidistant from r. if they are randomly located, the perpendicular line you create will not necessarily go through point r, hence will not be a solution to the problem.
