Answer:

Additive inverse property

Step-by-step explanation:

When you add opposites you get 0.

Another word for opposites is additive inverses.

This is the additive inverse property.

It says when you do -a+a or a+(-a) you get 0 for any number a.

X^4-256=0 numbers of rational roots
zhuklara [117]

Answer:

x = 8 or x = -8

Step-by-step explanation:

x^4 - 256 = 0

<=>x^4 - 4^4 = 0

<=>(x - 8)(x + 8)(x^2 + 64) = 0

Case 1 :

x - 8 = 0

<=>x = 8 (choose)

Case 2:

x + 8 = 0

<=>x = -8 (choose)

Case 3:

x^2 + 64 = 0

<=>x^2 = -64 (nonsense)

so x = 8 or x = -8

Done :))

A pair of shoes costs $70.00. How much will the customer pay after 7% sales tax is added to the purchase?
ANEK [815]

Answer:

$74.90

Step-by-step explanation:

If $70 is your original price, you would need to multiply it by 1.07, because that is 107%.

Since the original price is 100% of the price, and sales tax is another 7% of the price, you are multiplying the original price by 107%, again making $74.90.

Do you understand?
