The equation and table below represent one function.

Name the property of real numbers illustrated by the equation.

Ivanshal [37]

Alright, let's go through what these mean
- A is saying that you can group numbers in parenthesis differently for multiplication. Since this does not involve multiplication, this is not applicable.
- B is saying that you can expand numbers in parenthesis by multiplying it out.Since this does not involve multiplication, this is not applicable.
- C is saying that numbers multiplied by each other can be switched. Since this does not involve multiplication, this is not applicable.
- D is saying that you can group numbers in parenthesis differently for addition . Since this involves grouping numbers differently in parenthesis, this is correct!

How do I factor the following equation in the link? It has been factored, but I need to know the steps.

Vlad [161]

Given

$2x^2-x-3=0$

How to factor

Solution

Step 1

Multiply the first and last costant

$-3\times2x^2=-6x^2$

Step 2

Write out all the pair factors of -6x^2

$\begin{gathered} -6x^2=-6x\text{ and x} \\ -6x^2=-x\text{ and 6x} \\ -6x^2=\text{ -3x and 2x} \\ -6x^2=\text{ -2x and 3x} \end{gathered}$

Step 3

Check for the pair, such that when you add you will get -x

$\begin{gathered} it\text{ is } \\ -3x+2x=-x \\ \therefore-3x,\text{ 2x} \end{gathered}$

Step 4

Replace -x with -3x+2x in the equation

$2x^2-3x+2x-3=0$

Step 5

Put them into brackets Since + is at the center no stress.

$(2x^2-3x)+(2x-3)=0$

Step 6

Factor out what is common in the bracket

$x(2x^{}-3)+1(2x-3)=0$

Step 7

What is in the bracket are the same, pick one

$\therefore(2x-3)(x+1)=0_{}$

A group of 12 students are making 60 posters to advertise for a bake sale. How many posters does each student have to make in or

stich3 [128]

Answer:

each student must make 5 posters in one hour

Step-by-step explanation:

The equitable thing is that each student makes an equal number of posters at the established time, knowing that there must be 60 posters and there are 12 students, these numbers must be divided so we will have the same amount for each student:

60/12 = 5

Which means that each student must make 5 posters in one hour so that everything turns out well

What advantages does the graphing calculator have when it comes to finding the solution to a system of linear equations? Explain

Mashcka [7]

For this case you have the following advantages:

1) you can see the graph of both equations

2) you can see where the equations intersect

3) the point of intersection represents the solution to the system of equations.

4) You can solve the problem in much less time than doing it by hand

5) You can find very accurate solutions.

Given the information in the picture, which trigonometric identity can be used to solve for the height of the blue ladder that i

Stells [14]

The trigonometric identity can be used to solve for the height of the blue ladder that is leaning against the building is $\rm sin=\dfrac{o}{h}$ .

We have to determine

Which trigonometric identity can be used to solve for the height of the blue ladder that is leaning against the building?.

<h3>Trigonometric identity</h3>

Trigonometric Identities are the equalities that involve trigonometry functions and hold true for all the values of variables given in the equation.

Trig ratios help us calculate side lengths and interior angles of right triangles:

The trigonometric identity that can be used to solve for the height of the blue ladder is;

$\rm Sin47=\dfrac{50}{H}\\\\H=\dfrac{50}{sin47}\\\\H=68 feet$

Hence, the trigonometric identity can be used to solve for the height of the blue ladder that is leaning against the building is $\rm sin=\dfrac{o}{h}$ .
