Following are the solution to the given question:

Step-by-step explanation:

Please find the attached file of the graph:

In the question by adding through 4, Y's value is the amount you now have that I choose 3 as x value. 3+4=7 So

If x=3, y=7, Then chose the value x  that is 4 and −6 When x=-10, y=-6

by putting the ruler value through each of them and draw a line, that extend the line to the graphical edge field.

Answer:

[tex](a) x^2-2x=x \times (x+2) \\\\(b) 6x^2+12x=2\times 3 \times x \times ( x + 2) \\\\(c) 3x^3 - 9x=3\times x \times (x^2 -3) \\\\(d) 4x^2 +28 x^3 = 2 \times 2 \times x \times x \times ( 1+ 7x)[/tex]

Step-by-step explanation:

To factorize, at first, do factorize all the terms then take the common terms out.

(a) [tex]x^2-2x[/tex]

This can be written as

[tex]x^2-2x= x\times x + 2 \times x[/tex]

Now, taking x commom from both the terms.

[tex]x^2-2x=x \times (x+2)[/tex]

(b) [tex]6x^2+12x[/tex]

[tex]=2\times 3 \times x\times x + 2\times 2 \times 3 \times x[/tex]

Now, taking [tex]2\times 3\times x[/tex] common from both the terms, we have

[tex]6x^2+12x=2\times 3 \times x \times ( x + 2)[/tex]

This is the required factorization.

(c) [tex]3x^3 - 9x \\\\[/tex]

[tex]= 3 \times x \times x \times - 9\times x \\\\ 3x^3 - 9x=3\times x \times (x^2 -3)[/tex]

This is the required factorization.

(d) [tex]4x^2 +28 x^3[/tex]

[tex]= 2 \times 2 \times x \times x + 2 \times 2 \times 7 \times x \times x \times x \\\\4x^2 +28 x^3 = 2 \times 2 \times x \times x \times ( 1+ 7x)[/tex]

This is the required factorization.

Answer:

3.145 Hours

Step-by-step explanation:

37÷2=18.5

18.5×.17=3.145

It will take the tortoise to catch up with the hare 109 hours.

Given that,
A giant tortoise travels at 0.17 miles per hour and an arctic hare travels at 37 miles per hour. If The tortoise and the hare start out together and after half an hour the hare stops to take a rest. How long it takes the tortoise to catch up is to be determined.

Speed is defined as when an object is in motion, the distance covered by that object per unit of time is called speed.

Here,
Distance traveled by hare in half hour,
= speed * time
= 37 * 1/2
= 18.5 miles

Time is taken by the tortoise to catch up with the hare,
= distance / speed
= 18.5 / 0.17
≈ 109 hours

Thus, it will take the tortoise to catch up with the hare 109 hours.

Answer:

geometric, dividing by 3 every time

Step-by-step explanation:

Answer:

This is a geometric sequence and the common ratio is equal to 1/3

===========================================================

Explanation:

The sequence is not arithmetic because the gap between 45 and 15 is not the same as the gap from 15 to 5

Note how

Showing that we dropped by 30 when going from 45 to 15, but then we dropped by 10 when going from 15 to 5.

This gap or jump must be the same to have an arithmetic sequence.

--------------------

This sequence is geometric though.

We can see that by dividing each term by its previous term

Each time we get the same result 1/3 after reducing. If we didn't get the same result each time, then this sequence wouldn't be geometric.

But since we do get the same result each time, this tells us that the common ratio is 1/3. Each new term is 1/3 that of the previous term

For instance,

term2 = (1/3)*term1 = (1/3)*45 = 15

Answer:

This is a greatest common factor problem.

What is the greatest common factor of 18 and 30?

18 is 1 x 18: 2 x 9; 3 x 6

30 is 1 x 30: 2 x 15: 3 x 10; 5 x 6

Our greatest common factor is 6.

How many 6 inch boards can you cut from 18 and 30 inches.

18/6 = 3

30/6 = 5

Or, when you find the GCF, it's multiple is the number of boards at that length that can be cut.

What equation?

Answer:

80x-460=300

80x=760

Step-by-step explanation:

In order to know which equation is best, you have to add the total expenses the robotics club had.

Expenses:

Let's add: $400 + $60 = $460

Next, you have to know how many of the shirts were purchased.

Now, let's compute.

or

This means that the robotics club has to sell the shirts at $9.5 each in order to have a $300 profit.

Trying to factor as a Difference of Cubes

2.1 Factoring: 8x2y3-5

Theory : A difference of two perfect cubes, a3 - b3 can be factored into

(a-b) • (a2 +ab +b2)

Proof : (a-b)•(a2+ab+b2) =

a3+a2b+ab2-ba2-b2a-b3 =

a3+(a2b-ba2)+(ab2-b2a)-b3 =

a3+0+0+b3 =

a3+b3

Check : 8 is the cube of 2

Check : 5 is not a cube !!

Ruling : Binomial can not be factored as the difference of two perfect cubes

Final result :

8x2y3 - 5
