What is StartAbsoluteValue 8 EndAbsoluteValue?
Minchanka [31]

The absolute value of 8 that is |8| is equal to 8.

We have given that,

|8|

We have to determine the value of |8|.

<h3>What is the absolute value?</h3>

The absolute value or modulus of a real number x denoted |x|, is the non-negative value of x without regard to its sign. Namely, {\displaystyle |x|=x}if x is a positive number, and {\displaystyle |x|=-x} if x is negative, and {\displaystyle |0|=0}.

Absolute values only find the true distance of a number from 0. Distance is always positive, so the absolute value of anything is always positive.

|8| = 8

How to simplify an expression with a negative exponent
svetlana [45]

Answer:

Step-by-step explanation:

An negative exponent seems hard, but it really isn't!

Let's say you have 2^{-3}

All you do is inverse the expression, or find the reciprocal. When you do this the exponent changes to positive .  

\frac{1}{2^{3} }

2^{3} simplifies into 8. So, the result is

\frac{1}{8}

Hope this helps! Please mark as brainliest, thanks!

Radda [10]

Complete question :

Chuck lives 4/5 of a mile from the post office. He walked 2/3 of the way from home to the post office. How far did Chuck walk? If possible, write the answer in reduced form

Answer:

8/ 15 miles

Step-by-step explanation:

Given that:

Distance from house to post office = 4/5 miles

Distance walked = 2/3 of the distance

Hence, the distance walked can be obtained thus :

2/3 of (4/5)

2/3 * 4/5

8 / 15

Hence, Chucks walked 8 /15 miles

Examine the quadratic equation 9x^2+12x +4= 0.
mestny [16]

Answer:

See answers and explanations

Step-by-step explanation:

A) Discriminant = b² - 4ac = (12)² - 4(9)(4) = 144 - 144 = 0

B) Since the discriminant is 0, this means the equation only has one root.

C) The root is real in this case since the discriminant is not negative. Otherwise, we would have two imaginary roots if it were (remember that complex roots come in pairs)
