3) ponder the following linear programming problem:
min z = 3x1 + 8x2
subject to: 3x1 + 4x2 ≥ 52
3x1 + 4x2 ≥ 38
x1, x2 ≥ 0
a)what is minimum cost and the value of x1 and x2 at the optimal solution?
b) show the graphical solution!

step-by-step explanation:

this is not a question

x + y = 90 5x – 10y = 90 90 – 10y = 5x 90 + 10y = 5x

step-by-step explanation:

last month maria hiked the 5-mile mountain trail a number of times and she hiked the 10-mile canal trail several times. let x represent the number of times she hiked the 5-mile trail, and let y represent the number of times she hiked the 10-mile trail. if she hiked a total of 90 miles, which equation can be used to find the number of times maria hiked each trail? x + y = 90 5x – 10y = 90 90 – 10y = 5x 90 + 10y = 5x

47 - 90 = 43

43 - 180 = x

x = 137

answer: 5100 just subtract
