Step-by-step explanation:

<em>2</em><em>x</em><em>(</em><em>x-5</em><em>)</em><em>+</em><em>3</em><em>(</em><em>x-2</em><em>)</em><em>=</em><em>8</em><em>+</em><em>7</em><em>(</em><em>x-4</em><em>)</em>

<em>2</em><em>x</em><em>²</em><em>-10x</em><em>+</em><em>3</em><em>x</em><em>-</em><em>6</em><em>=</em><em>8</em><em>+</em><em>7</em><em>x</em><em>-</em><em>2</em><em>8</em><em>(</em><em>Group</em><em> </em><em>like</em><em> </em><em>terms</em><em>)</em>

<em>2</em><em>x</em><em>²</em><em>-</em><em>1</em><em>0</em><em>x</em><em>+</em><em>3</em><em>x</em><em>-</em><em>7</em><em>x</em><em>=</em><em>8</em><em>-</em><em>2</em><em>8</em><em>+</em><em>6</em>

If f(x) = 1-x2 and g(x) = 1 - x which is the rule of function (f – g)(x)?
V125BC [204]

Answer:

-x^2 +x

Step-by-step explanation:

f(x) = 1-x^2

g(x) = 1 - x

f(x) - g(x) = 1-x^2  - (1 - x )

Distribute the minus sign

              = 1-x^2 -1 +x

Combine like terms

             = -x^2 +x

The double number line shows that Kimimela
slega [8]

The completion of the table showing the different percentages of the days that Kimmimela and her foster brother fed the rabbits this year is as follows:

<h3>Rabbit Feeding Table:</h3>

Person     Time (days)    Percentage

Kimimela         350             95.9%

Foster Brother   15                4.1%

<h3>What is a percentage?</h3>

A percentage is a mathematical expression of a number or ratio as a fraction of 100.

A percentage is often denoted with the percent sign, "%."

Most importantly, a percentage shows the relative value of a variable out of the hundredth parts of the class.

For instance, this question showed that Kimimela fed her rabbits 350 out of 365 days of this year. This implies that her foster brother fed the rabbits for 15 days (365 - 350).

<h3>Data and Calculations:</h3>

Person     Time (days)    Percentage

Kimimela         350             95.9% (350/365 x 100)

Foster Brother   15                4.1% (15/365 x 100)

Total               365               100%

Thus, we can conclude that Kimimela fed the rabbits <u>96%</u> of the days.

Which of the following represents the reflexive property of length? Question 6 options: A) m∠A = m∠A B) If AB = CD, then CD = AB
poizon [28]

Answer:

D) AB = AB  

Step-by-step explanation:

The reflexive property states that a value is equal to itself: x = x.

The reflexive property of length states that a length is equal to itself:

AB = AB

A) and C) are wrong. They represent the reflexive property of angles.

B) is wrong. It represents the symmetric property of length.
