Miley music has a sale on music CDs all music CDs are discounted 15% Marianas receipt indicates that she saved $3 on her CD purchase what is the full price of her music CD before the discount

Answers

Answer: The original price of her music CD before discount is $20.

Step-by-step explanation:

Let x be the original price of her music CD.

Discount rate = 15%

At discount she saved = $3

So, According to question, our equation becomes

15%x= 3

0.15x= 3

x=$20

Hence, the original price of her music CD before discount is $20.

If x is the price before a sale
x-0.15x=x-3
0.85x=x-3
3=0.15x
x=20

The original price is $20

Write an algebraic expression to represent the new y-coordinate after a translation of four yards south given any initial y-coordinate, y.

Answers

An algebraic expression that can be used to represent the new y-coordinate after a translation of four yards south is y-4.

What is an Expression?

In mathematics, an expression is defined as a set of numbers, variables, and mathematical operations formed according to rules dependent on the context.

Let's assume that 1 unit represents 1 mile.

Given that the present coordinate of the point is y. Now, if the point is moved towards the south, then the point will be shifted to 4 units sown. Therefore, we can write an algebraic expression to represent the new y-coordinate after a translation of four yards south as,

New-coordinate = y - 4

Hence, an algebraic expression that can be used to represent the new y-coordinate after a translation of four yards south is y-4.

Factor completely x2 − 10x + 25.(x − 5)(x − 5)

(x + 5)(x + 5)

(x + 5)(x − 5)

(x − 25)(x − 1)

Answers

The answer is:
(x - 5) (x - 5) The equation is a perfect square.
(a - b) (a - b) The "formula" goes a^2 - 2ab + b^2 for this equation so when you expand out the brackets x to x, x to 5 then 5 to x and 5 to 5 ( a x a, a x b, b x a, b x b) then collect all the like terms it turns into the equation above.
