What is the maximum value of the objective function, P, with the given constraints?
Gala2k [10]

Answer:

C. 450

Step-by-step explanation:

Plot the solution area for the system of four inequalities

\left\{\begin{array}{l}4x+y\le 16\\x+y\le 10\\x\ge 0\\y\ge 0\end{array}\right.

You'll get the quadrilateral with vertices at points (0,0), (0,10), (2,8) and (4,0).

The maximum value of the function can be at vertices, so

P=25x+45y\\ \\P(0,0)=25\cdot0+45\cdot 0\\ \\P(0,10)=25\cdot 0+45\cdot 10=450\\ \\P(2,8)=25\cdot 2+45\cdot 8=50+360=410\\ \\P(4,0)=25\cdot 4+45\cdot 0=100

The maximum value of the function is 450 at point (0,10)

Given g(x) = 3x + 14 , find x if g(x) = 20
Helga [31]

Answer: x = 2

Step-by-step explanation: If g(x) = 3x + 14, and g(x) = 20 also, you first can set 3x+14 = 20. To find the value of x, you want to isolate the variable. You can subtract 14 from both sides to get 3x = 6. Finally, to find out the value of x, divide 3 from both sides. This leaves you with x = 2. You can check this by plugging two back into the original equation 3 times 2 = 6, and 6 plus 14 equals 20.

What should be added to a²-2ab+b² to get a²-ab-2b² ​
dybincka [34]

<u>SOLUTION</u><u>:</u>

<u>what should be added to a²-2ab+b² to get a²-ab-2b² </u>

let the added no is P

  • \pmb{P+(a^2-2ab+b^2)=(a^2-ab-2b^2) }

  • \pmb{P=(a^2-ab-2b^2)-(a^2-2ab+b^2) }

  • \pmb{P=a^2-ab-2b^2-a^2+2ab-b^2 }

  • \pmb{P=ab-3b^2 }

\therefore{\pmb{ab-3b^2 }} should be added to a²-2ab+b² to get a²-ab-2b²
