There is a requirement of 176 packets of economy blend and 96 packets of a superior blend to make maximum profit for the week.

Using the given data, calculate the x number of packages of the economy blend as well as the y number of packages of the superior mix.

3x + 11y =1584

6x + 4y = 1440

From the graph of these two equations, three extreme points are deduced: (240,0), (0,144), and (176,96).

The maximum (2x +4y) is the goal function.

Determine the aim function's value at all these extreme points,

The objective function value for (240,0) is 2 × 240 = 480

The objective function value for (0,144) is 4 × 144 = 576

The value of the objective function for (176,96) is 2 × 176 + 4 × 96 = 736

∴ The optimal point is (176,96) where x = 176 and y = 96.

The number of  items you would need to sell at your chosen price to break even is; 120 items

We are given the expression that represents the cost of producing x items as;

Cost of producing x units: C = 120 + 4x.

Now, we are told to decide on a selling price for each item. If we decide that the selling price for each item is $5, then it means that;

Revenue generated by selling x units at the rate of $5 per unit is;

R = 5x

For the chosen price to break even, it means that revenue must be equal to cost. Thus;

R = C

Thus;

5x = 120 + 4x

Step-by-step explanation:

Answer: 310000000

Step-by-step is provided in the picture below!

A linear equation is a mathematical form of a line segment the point (6,5) satisfies the equation y = 2/3x + 1 so it is the solution of the equation but (9,8) is not the solution.

A straight line on the coordinate plane is represented by a linear function.

The formula for a linear function is f(x) = ax + b, where a and b are real values.

As per the given linear equation, y = 2/3x + 1

To be a point of its solution the point must satisfy the given equation.

Substitute (6,5)

5 = (2/3)6 + 1

5 = 2(2) + 1 = 5

Therefore, the (6,5) is the solution of the equation.

Substitute,(9,8)

(2/3)9 + 1 = 7

8 ≠ 7

So,(9,8) is not the solution of the equation.

Hence "A linear equation is a mathematical form of a line segment the point (6,5) satisfies the equation y = 2/3x + 1 so it is the solution of the equation but (9,8) is not the solution".

The Bank discount and proceeds of the given information is:

$2365.27 and $47634.73 respectively.

Given the face value is $50,000

Discount rate = 13%

No.of term days = April 5 to August 14

= 131 days.

Bank discount = ?

Proceeds = ?

First calculate the bank discount using the formula:

Bank discount = face value × discount rate × time

Bank discount = $50,000 × 0.13 × 131/360

= 50,000×0.13×0.36388

= $2365.27

now calculate the proceeds using the formula :

Proceeds = face value - bank discount

= 50,000 - 2365.27

= $47634.73

Hence the bank discount and proceeds are $2365.27 and $47634.73 respectively.

Answer:

  5 and -3

Step-by-step explanation:

You want two integers that have a sum of 2 and a product of -15.

Solving a problem like this can often be done fairly quickly by listing the factor pairs that make up the product. Only the pairs need be listed that have a sum with the same sign as the sum you're looking for.

Divisors of 15 are 1, 3, 5, and 15. You want a negative product with the largest factor being positive:

  -15 = 15(-1) = 5(-3)

The sums of these factor pairs are 14 and 2. The latter pair is the one of interest.

The two integers are 5 and -3.

__

Additional comment

The desired relations can be expressed as a quadratic equation. It generally works well to solve it by completing the square.

If one of the numbers is x, the other is 2-x. Their product is -15:

  x(2 -x) = -15

  2x -x^2 = -15 . . . . . eliminate parentheses

  x^2 -2x = 15 . . . . . . make the leading coefficient positive

Complete the square by adding the square of half the x-coefficient

  x^2 -2x +1 = 15 +1

  (x -1)^2 = 16

  x -1 = √16 = 4 . . . . . . take the square root

  x = 5 . . . . . . . . . . . add 1

  2-x = 2 -5 = -3 . . . . the other number

To solve this problem we ned to isolate the "w" variable on the left side of the equation, as shown below:

The correct answer is the second option.

Answer: These linear functions can be represented by two lines y = 5x and y' = 5x' + 3

So when we shift line y = 5x by 3 units up on the y-axis then a new graph of

y = 5x + 3 will be formed.

Therefore, Option A is the answer.

Answer:

answer D is right. You need to substract,so that you can get x=2

real number can be a complex number but a complex number can not be a real number, verified.

the lengths of the complex number and its conjugate are equal but the converse is not necessarily true., verified.

Not all complex numbers are real numbers, despite the fact that every complex number is a real number.

In fact, determining whether the complex number z = a + bi is real is one of the complex conjugate's most useful applications. If and only if z = a + 0i, a complex number is real. In other words, a complex number is real if it contains an imaginary part.

Mathematical proof:

Let z = a+bi, where a and b = real numbers.

Let z* =complex conjugate of z.

Then the magnitude (absolute value) of z is:

|z| = √(a²+b²).

And the value of z* is:

|z*| = √[a²+(-b)²] = √(a²+b²).

So |z| = |z*|.

This Completes the Proof.

The equation that could model the given situation is y = -x + 30.25. The correct option is B. y = -x + 30.25

From the question, we are to determine the equation that could model the given situation

The perimeter, P, of a rectangle is given by the formula,

P = 2(l + w)

Where P is the perimeter

l is the length

and w is the width

From the given information,

The perimeter of a rectangular room is 60.5 feet.

∴ P = 60.5 feet

Also,

x is the width of the room and y is the length of the room

That is,

l = y

and

w = x

Thus,

The equation becomes

60.5 = 2(y + x)

2(y + x) = 60.5

Divide through by 2

y + x = 30.25

y = -x + 30.25
