The price-demand relationship of the company is a linear model

The equation that models the price-demand relationship is y = -20x + 1960

From the question, we have the following points:

(x, y) = (88, 200) and (38, 1200)

The equation of the linear relationship is then calculated as:

[tex]y = \frac{y_2 - y_1}{x_2 -x_1} * (x - x_1) + y_1[/tex]

Substitute known values in the above equation

[tex]y = \frac{1200 - 200}{38 -88} * (x - 88) + 200[/tex]

Evaluate the difference

[tex]y = \frac{1000}{-50} * (x - 88) + 200[/tex]

Evaluate the quotient

[tex]y = -20 * (x - 88) + 200[/tex]

Expand

[tex]y = -20x + 1760 + 200[/tex]

Evaluate the sum

[tex]y = -20x + 1960[/tex]

Hence, the equation that models the price-demand relationship is y = -20x + 1960

Option B

Step-by-step explanation:

→ It cannot have a bx coefficient in ax² + bx + c which eliminates all but 1 option

Answer:

  B.  (x +4)(x -4)

Step-by-step explanation:

The x-intercepts are shown on the graph to be at x=-4 and x=4. For x-intercept p, there is a factor (x-p). That means the factored form is ...

  (x -(-4))(x -(4)) = (x +4)(x -4)

_____

Additional comment

The product of these factors is x^2 -16, consistent with the vertex on the graph being located at (0, -16).

Answer:

Dogs: 44.44 Cats: 55.556

Step-by-step explanation:

*this is only if you are allowed to use a calculator*

1. You have to add the total of the cats and dogs

Why? Here, let me put it this way. You have a test with two sections: math and science. If there are 2 Maths Questions and 2 Science questions, what percent of the test are math questions? You would not say 2/2 and say 100. You would say 2/4 because it is obvious. You do the same in this case but it is not as noticeable because you are dealing with bigger numbers.

15 + 12 = 27.

2. Solve

a. There are 15 dogs and 12 cats that makes up 27 pets total.

So you have to do 12/27 for cats,

15/27 for dogs. The fractions equal one and It shows you how much of one is there compared to the total.

b. Simplify

You can simplify these fractions:

for 12/27, divide the numerator and the denominator by 3.

You get 4/9

Divide 15/27 for dogs by 3 as well to get 5/9.

5+4 is 9, which means that I am doing the math correctly.

According to the calculator, 5/9 is 55.556, and 4/9 is 44.444

They should be accurate because there are more dogs than cats and the percentage for dogs are higher. Hence, this is correct.

Cats = 4/9 = 44.444%

Dogs = 5/9 = 55.556%

Hope this helps :)

[tex] \frac{1}{2} (29 - x) = 7.75[/tex]

[tex] \frac{1}{2} ( - x + 29) = 7.75[/tex]

[tex] \frac{1( - x + 29)}{2} = 7.75[/tex]

[tex] \frac{ - x + 29}{2} = 7.75[/tex]

[tex]2· \frac{ - x + 29}{2} = 2·7.75[/tex]

[tex] - x + 29 = 2·7.75[/tex]

[tex] - x + 29 = 15.5[/tex]

[tex] - x + 29 = 15.5 - 29[/tex]

[tex] - x = - 13.5[/tex]

[tex] \frac{ - x} {- 1} = \frac{ - 13.5 }{ - 1 } [/tex]

The estimated value of a motorcycle that is 5 years old is $4750.

A linear equation is in the form:

y = mx + b

Where y,x are variables, m is the rate of change and b is the initial value of y.

Let y represent the value of the motorcycle after x years.

The value is given by:

y = -750x + 8500

After 5 years (x = 5):

y = -750(5) + 8500 = 4750

The estimated value of a motorcycle that is 5 years old is $4750.

Step-by-step explanation:

 k = 2

The point (0, 0) on the graph of f(x) tells you f (0) = 0.

The point (-4, 0) on the graph of g(x) tells you g (-2) = 0.

Now we know that

 g(-2) = 0 = f(0) = f(-2+k)

or ...

 0 = -2+k

 2 = k

The value of k is 2

so the answer to you problem is k=2

The preparation of the Sales section of the income statement for Blue Spruce Corp. is as follows:

BLUE SPRUCE CORP.

For the year ended October 31, 2022

Sales Revenue                         $908,400

Sales Returns and Allowances  (20,900)

Sales Discounts                           (14,700)

Net sales revenue                  $872,800

The net sales revenue represents the gross revenue minus sales returns and allowances and sales discounts.

In most jurisdictions, the sales discount account is reported on the income statement as a contra revenue account.  This implies that sales discounts are directly deducted from the gross sales and do not appear in the expense section nor the notes to the sales or revenue.

Sales Revenue $908,400

Freight-Out $12,600

Sales Returns and Allowances $20,900

Sales Discounts $14,700

Thus, the preparation of the sales section of the income statement for Blue Spruce Corp. shows a net sales revenue of $872,800.

The value of A in solving the considered quadratic equation by completing the squares method is given by: Option

Suppose the considered quadratic equation is of the form [tex]ax^2 + bx + c = 0[/tex]

Then, completing the squares method tries to make a squared term in terms of x in the left side, so that x comes in linear form, instead of quadratic, as shown below:

[tex]ax^2 + bx + c = 0\\ax^2 + bx = -c\\\\\text{Multiplying 4a on both the sides}\\4a^2x^2 + 4abx = -4ac\\\\\text{Adding }b^2\text{ on both the sides}\\4a^2x^2 + 4abx + b^2 = b^2 -4ac\\or\\(2ax +b)^2 = b^2 - 4ac\\2ax + b = \pm \sqrt{b^2 - 4ac}\\\\x = \dfrac{-b \pm \sqrt{b^2 - 4ac}}{2a}[/tex]

This provides two solution to the considered quadratic equation. These solutions can be real, or imaginary.

For the considered case, the quadratic equation is:

[tex]10x^2 + 40x - 13 = 0[/tex]

Applying the method as Isoke did, we get:

[tex]10x^2 + 40x - 13 = 0\\10x^2 + 40x = 13\\10(x^2 + 4x) = 13[/tex]

Therefore, we get the value of A as 10.

The scatterplot can show an association or no association, at all.

The type of association shown by the graph that relates test grades and shoe sizes of the students in Dexter's class is no association

When the points on the graph of the scatter plot follows an approximately, straight line; then the relationship is a linear relationship.

If it follows a curve, then it is a nonlinear relationship

If the points are scattered, then it shows no association.

The points on the graph are scattered, and they do not follow a specific pattern.

Hence, the graph shows no association
