What is a solution of the inequality p +4-2 (p-10)>0

Mathematics

Troyanec [42]3 years ago

First we distribute -2 into p and -10.

<span>p + 4 - 2 (p - 10) > 0

-2 x p = -2p
-2 x -10 = 20

After that, you'll get 

p + 3 - 2p + 20 > 0

Then we must add like terms.

-2p + p = 1p or p
3 + 20 = 23

After that you'll get

p + 23 > 0

Our goal is to get 'p' by itself, so we must subtract 23 on both sides of the inequality.

</span>p + 23 > 0
    - 23  -23

So, p > -23 is the answer

This is a full assignment I’m struggling on if someone can answer them all and get most correct I will give you Brainliest for y
Effectus [21]

Answer:

Step-by-step explanation:

a) 1) Polynomial is closed under addition. In polynomial addition, only the coefficient change and variables and it powers does not change.

Example: Add 3x² - 2x + 7  and -2x² - 5x + 3

3x² - 2x + 7 - 2x² - 5x + 3 = 3x² -2x² - 2x - 5x + 7 + 3

= x² - 7x + 10

2)Polynomial    is closed under addition. In polynomial subtraction, only the coefficient change and variables and it powers does not change.

Example: Subtract 3x - 2 from 4x + 2

4x + 2 - (3x - 2) = 4x + 2 - 3x + 2  = 7x + 4

3) Polynomial is closed under multiplication. In this, exponents of the variables are added according to the exponent rule. As the exponent of polynomials are whole numbers and whole numbers are closed under addition, the result will be a whole number.

-2x³ * 3x² = -3*x^{3+2}=-3x^{5}

4) Polynomial is not closed under multiplication. In division, we may get a negative exponent. So, it is not closed under division.

\dfrac{x^{4}}{x^{9}}=x^{4-9}=x^{-5}\\\\x^{-5} \ is \ not \ a \ polynomial.

                                 Addition        subtraction  multiplication   Division

Natural numbers          yes             not closed    Yes                   Not closed

Integers                        Yes                 Yes              Yes                   not closed

Rational numbers         Yes                 Yes              Yes                     not closed

Irrational numbers       not closed   not closed   not closed   not closed

The total employment for police officers in 2006 was 648,000. If there are 719,000 police officers in 2016, what will the percen
Lubov Fominskaja [6]
If you increase the number of police officers from 648,000 to 719,000...you have increased the total employment by 719,000 minus 648,000 
= 71,000

You want to see how much the percentage increase was from 2006 to 2016, so you use your 2006 value of police officers to find the percentage increase.

So you divide 71,000 by 648,000 and multiply by 100 
=10.957%

Rounded off to 10.96% which is your final answer
