Graph the system of constraints and find the value of x and y that maximize the objective function.

Constraints {x >= 0
y >= 0
y <= 3
y <= -x+5}

Objective Function C=-5x+3y

a) 0,0
b) 2,3
c) 5,0
d) 0,3

I am a mom going crazy. I did horrible in math in school. Someone please help. Thank you

  1. This is not that hard

    x≥ 0 , everthing to the right of the y-axis
    y≥ 0 , everthing above the x-axis
    So far you are in quadrant I of the x-y plane

    y ≤ 3 , everthing from the above, but also below the horizontal line y = 3

    lastly y ≤ -x + 5
    sketch a line leaning 45° to the left with a y-intercept of 5, shade in everthing below that line
    My diagram has a simple trapezoid consisting of a
    rectangle with a right-angled triangle attached

    now our Objective Function is
    C = -5x + 3y , which is a line with slope 5/3
    letting that line go through the origin, let it slide parallel to itself over the shaded region until you reach the farthest point from the origin.
    On my diagram that looks like (5,0)

  9. I just took the Unit 4: Lesson 6: Quiz Part 1. The answers are:

    1. D (0,3)
    2. A (20 of type A; 20 of type B)
    3. D (no solution)
    4. A (-5)
    5. D (11 -12 | 7)
    (5 12 | -7)
    6. A (-6, 8)

    These are 100% correct I just took the quiz.

  11. I just took the Unit 4: Linear Systems | Lesson 6: Solving Systems Using Matrices Quiz Part 1. These are my answers.
    1.) C~ (5,0)
    2.) A~ 20 of type A; 20 of type B
    3.) D~ no solution
    4.) A~ -5
    I got #5 wrong but I said C. The answer to #5 is not C. Unfortunately, it won't tell me the correct answer. :( I'm sorry. @//Just Helping says it's D.
    6.) A~ (-6, 8)

    I know how hard math can be, and I know how difficult it is to see the naturally more 'smart' students get rewarded while the students who work hard but can still never quite get to the same level as them get scolded. Hope this helped somebody :) Stay safe everybody

  16. You guys make no sense. Anyway maybe we have different numbers in the question... but if you have:
    "Graph the system of constraints and find the value of x and y that maximize the objective function.
    Constraints
    {x >= 0
    y >= 0
    y <= 3
    y <= -x+5}
    Objective Function C=-5x+3y"

    then the answer is (0,3) - which for me is D

    this is bc you are plugging it into the objective function to see basically which coordinates get you the biggest amount for C. - so solve it yourself if you want by just taking the answer choices and plugging each x value in for x in the objective function and each y value in for y in the objective function. Make sure you are using the objective function though not any of the constraints! Also I just submitted the test and got that right. Hope that helps some. If you want more help let me know and I've got the answers to the rest if any of you would like them as well.
