Answer:
the Ans is 3.4
Step-by-step explanation:
8(3x - 7) = -6(x + 7) + 4
24 x – 56 = -6x - 42 + 4
24x - 56 = -6x + 46
30 x = 102
X=3.4
How many solutions does this quadratic equation have?
y = x² + 10x + 25
Answer:
you can use interent mircosoft calculator
Step-by-step explanation:
Answer:
1
Step-by-step explanation:
y = x² + 10x + 25 ← is a perfect square
y = (x + 5)²
To find the solution let y = 0 , that is
(x + 5)² = 0, that is
x + 5 = 0 ⇒ x = - 5
The robotics club is selling shirts for a fundraiser. They have purchased a box of shirts for $400 at $5 per shirt. To promote their fundraiser, they have also spent $60 on advertising.
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:
box of shirts = $400advertising = $60Let's add: $400 + $60 = $460
Next, you have to know how many of the shirts were purchased.
$400 ÷ $5 = 80Now, let's compute.
80x - 460 = 30080x = 300 + 46080x = 760x = $9.5or
80x=760x = 760 ÷ 80x = $9.5This 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

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 does it take the tortoise to catch up
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
15-45 = -305-15 = -10Showing 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
term2/term1 = 15/45 = 1/3term3/term2 = 5/15 = 1/3Each 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:
[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.

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.
