How do you write and equation of a linear function using two points
Margaret [11]

Answer:

Step-by-step explanation:

Find the difference between the 2 points.

For example, (8, 9) (5, 3).

Compare the difference between the x's, in this case 8 and 5. The difference is 3. Do the same with the y's, 9 and 3. The difference is 6.

To find the slope, it's y/x. The slope in this situation is 6/3. Simplify. The slope is 2.

To find the y-intercept, insert the slope and one of the 2 points in the beginning into y = mx + b & solve for b.

For example, if we use the ordered pair (5, 3) the equation would look like:

3 = 2(5) + b, Solve for b.

Multiply. 3 = 10 + b

Get b by itself by adding - 10 to both sides.

-7 = b

The y-intercept is -7. So, in this case, the equation is y = 2x - 7.

Suppose Global Cable has declared a dividend of $2,500,000. The company has 240,000 shares of preferred stock that pay $2.10 per
Alika [10]

Answer:

$0.7676

Step-by-step explanation:

Dividend declared = $2,500,000.

Total shares of preferred stock = 240,000

Each share costs $2.10

So, Total cost of shares of preferred stock = 240,000×2.10

       Dividend due to the preferred shareholders  = $504,000.

Now,

Total shares of common stock = 2,600,00

Cost of shares of common stocks = Total dividend - Total cost of shares of

                                                                                       preferred stock

                                                           = $2,500,000-504,000

                                                           = $1,996,000

Dividend per share of common stock =$ \frac{1,996,000}{2,600,000}

                                                              = $0.7676

The length of a rectangle is (x^2- 4x+2) feet and the width is (x+4) feet
erastovalidia [21]

Answer:

A=x^3-14x+8

Step-by-step explanation:

Given that,

Length of a rectangle, l=(x^2- 4x+2)

Width of a rectangle, b=(x+4)

We need to find the area of the rectangle.

We know that,

Area of a rectangle = l × b

Substituting all the values,

A=(x^2- 4x+2)\times (x+4)\\\\=x^3+4x^2-4x^2-16x+2x+8\\\\=x^3-14x+8

Hence, the area of the rectangle is x^3-14x+8.

Mashcka [7]

Answer:

(2b - 3)(2b + 3)(b - 3)

Step-by-step explanation:

4b³ - 9b - 12b² + 27

b(4b² - 9) - 3(4b² - 9)

(4b² - 9)(b - 3)

(2b - 3)(2b + 3)(b - 3)
