A craftsman builds two kinds of birdhouses, one for wrens and one for bluebirds. Each wren birdhouse takes 3 hours of labor and

Ksenya-84 [330]

Answer:

Obj Function, Max P=8w+16b

Subject to the Constraints

3w+2l≤80

4w+10b≤100

w≥6

b>0

Step-by-step explanation:

Let the number of Wren's birdhouse built=w

Let the number of bluebirds birdhouse built=b

Constraint:Labour

Each wren birdhouse takes 3 hours of labor.

Each bluebird house requires 2 hours of labor.

The craftsman has available 80 hours of labor

Formulated as an inequality:

3w+2l≤80

Constraint: Lumber

Each wren birdhouse requires 4 units of lumber.

Each bluebird birdhouse 10 units of lumber.

The craftsman has available 100 units of lumber

Formulated as an inequality:

4w+10b≤100

The craftsman wants to build at least 6 wren houses.

w≥6

Since he builds the two kinds of house, b>0 and w>0.

Objective Function

Wren houses profit $8 each and bluebird houses profit $16 each.

The Objective of the function is to make profit, so we maximize.

Obj Function, Max P=8w+16b

The linear programming problem is therefore stated below:

Obj Function, Max P=8w+16b

Subject to the Constraints

3w+2l≤80

4w+10b≤100

w≥6

b>0

Elimination_4x_2y=14 _10x+7y=_24

Gnesinka [82]

Answer:

The answer is $x=-\frac{50}{8}$ and $y=\frac{11}{2}.$

Step-by-step explanation:

Given:

-4x-2y=14

-10x+7y=-24

Now, to solve it by elimination:

$-4x-2y=14$ ......(1)

$-10x+7y=-24$ ......(2)

So, we multiply the equation (1) by 7 we get:

$-28x-14y=98$

And, we multiply the equation (2) by 2 we get:

$-20x+14y=-48$

Now, adding both the new equations:

$-28x-14y+(-20x+14y)=98+(-48)$

$-28x-14y-20x+14y=98-48$

$-28x-20x-14y+14y=50$

$-8x=50$

Dividing both the sides by -8 we get:

$x=-\frac{50}{8}$

Now, putting the value of $x$ in equation (1):

$-4x-2y=14$

$-4(-\frac{50}{8})-2y=14$

$\frac{200}{8} -2y=14$

$25-2y=14$

Subtracting both sides by 25 we get:

$-2y=-11$

Dividing both sides by -2 we get:

$y=\frac{11}{2}$

Therefore, the answer is $x=-\frac{50}{8}$ and $y=\frac{11}{2}.$
