A proportional relationship is used to illustrate linear equations.

The constant of proportionality is 3

From the table, we have the following points:

(x,y) = (2,6) (3,9)

The constant of proportionality is calculated using:

\mathbf{m = \frac{y_2 - y_1}{x_2 - x_1}}

So, we have:

\mathbf{m = \frac{9-6}{3-2}}

Subtract

\mathbf{m = \frac{3}{1}}

Divide

\mathbf{m = 3}

Hence, the constant of proportionality is 3

Multiply the following and provide the product in standard from thank you
LekaFEV [45]

Answer:

x^3 + 4x^2 - 7x - 10

Step-by-step explanation:

To solve this we're going to use Polynomial multiplication, starting by multiplying (x-2)(x+1) = x^2 - 2x + x - 2 = x^2 - x - 2. Next, we will multiply (x^2 - x - 2)(x+ 5) = x^3 + 5x^2 -x^2 - 5x -2x -10 = x^3 + 4x^2 - 7x - 10.

A pair of skis was discounted 20%. How many percent will the discounted price have to be increased to return to the original pri
denis-greek [22]

Answer:

25%

Step-by-step explanation:

Let the original price of A pair of skis be $100

discount given on A pair of skis = 20% on original price

discount value of A pair of skis in $ = 20% * $100

                   =  (20 * 100)/100 = $20

discounted price of A pair of skis =  original price - discount = 100 -20 = $80

in order to increase discounted price to original price of $100

there must be increase of $20 to discounted price which is $80

percentage increase on discounted price   to return to the original price =

(increased \ amount / discounted \ price) * 100 \\=>( 20/80) * 100 =  25\\

therefore 25% must be increase on discounted price to return to the original price
