What is the solution set of –|x| = –8?

Answers

Answer 1

Answer:

Answer:

x=-8, 8

Step-by-step explanation:

–|x| = –8

$-|x| = -8$

To solve this absolute value inequality we remove the negative sign on the left hand side

Divide both sides by $-1$

$|x| =8$

If $|x|=a$ then $x=a \ and \ x=-a$

$|x| =8$

$x=8 \ and \ x=-8$

Answer 2

Answer: -|x|=-8 X=-(-8) X=8 I hope that is good!

A certain microscope is able to magnify an object up to 100,000 times its original size. In scientific notation, 100,000 is _____.

Answers

Answer: In scientific notation, 100,000 is $1.0*10^5$

Step-by-step explanation:

We know that the scientific notation is a technique to describe a very large or a very small number in the product of a decimal form of number [generally between 1 and 10] and powers of ten.

The given number = 100,000

Here the number of zeroes = 5

Then, in scientific notation, 100,000 = $1.0*10^5$

shift 5 decimal places to the left, so the exponent for base 10 is 5. Therefore, the number in scientific notation is:
1.0 x 105

hn and 4 friends are going out for pizza for lunch. They split one pizza and 5 large drinks. The pizza cost $10.00. After using a $4.00 gift certificate, they spend a total of $13.50. Write an equation to model this situation, and find the cost of one large drink.

Answers

5d + 10 - 4 = 13.50 <== ur equation
5d + 6 = 13.50
5d = 13.50 - 6
5d = 7.5
d = 7.5/5
d = 1.50 <== what each drink costs
