Answer:

So Price after discount would be 17.5 on February 1st

Step-by-step explanation:

Given:

Original Cost =57.75

Off Price = 70%

To Find:

Price after discount = ?

Solution:

We have to find the price after discount which is given by the formula

Price after Discount = Original Cost - Discount Price

We have to find the value of discount price

Discount Price = off Price * Original Cost

Putting in the values

Discount Price = 70 % * 57.75

it becomes

Discount Price $=\frac{70*57.75}{100}$

It becomes

$=\frac{4025}{100}$

= 40.25

Now

Price after Discount = Original Cost - Discount Price

Putting in the values

it becomes

Price after Discount = 57.75-40.25

= 17.5

So Price after discount would be 17.5 on February 1st

PLEASE ANSWER

Answer:

x² + 9x + 8 = (x + 1)(x + 8)

x² + 9x + 8 = (x + 8)(x + 1)

Step-by-step explanation:

* Lets explain how to factorize the polynomial using the pattern

- The form of the quadratic polynomial is x² + px + q, where p is the

coefficient of x and q is the numerical term

∵ x² + (a + b)x + (ab) = (x + a)(x + b)

- From the formula above the coefficient of x is the sum of the two

factors a and b

∴ p = a + b and q = ab

- That means p is the sum of two numbers and q is the product of

the same numbers

* Lets solve the problem

∵ x² + 9x + 8 is a quadratic polynomial

∵ x² + px + q is the form of quadratic polynomial

∴ p = 9 and q = 8

∵ p = a + b and q = ab

∴ a + b = 9 ⇒ (1)

∴ ab = 8 ⇒ (2)

- We must to find two numbers their product is 8 and their sum is 9

∵ The possibility of 8 as a product of two numbers is:

2 × 4 OR 1 × 8

∵ The sum of 1 + 8 = 9

∴ The value of a and b are 1 and 8

- It does't matter which of them = 1 or which of them = 8

∴ x² + (a + b)x + ab = x² + (1 + 8)x + (1)(9)

∵ x² + (a + b)x + (ab) = (x + a)(x + b)

∴ x² + (1 + 8)x + (1)(9) = (x + 1)(x + 8)

∴ x² + 9x + 8 = (x + 1)(x + 8)

- OR

∴ x² + 9x + 8 = (x + 8)(x + 1)

What is the costant of proportionality in the equation y=2.5x

andrew-mc [135]

Answer:

$k=2.5$

Step-by-step explanation:

$y \propto x$

$y=kx$

$k$ is the proportionality constant.

$y=2.5x$

The $y$ is the independent variable and $x$ is the dependent variable.

The proportionality constant is $2.5$ .
