Answer:

The mistake happens in the 4th line.

Step-by-step explanation:

The first 3 lines are correct until the 4th line which is 2=6x. This is wrong. If we go back a line to the third line, it is 22=-20+6x. The part that was wrong was that they subtracted 20 from 22 to get 2. We are supposed to add 20 to each side because the -20 is negative. So the 4th line should be 42=6x. Then, we know that 6 times 7 is 42, so x is equal to 7.

22 + 53x + x = -20 + 60x

22 + 54x = -20 + 60x

22 = -20 + 6x

42 = 6x

x = 7

Answer: y + 4 = -3(x+1)

Step-by-step explanation:

We need to rewrite in form of y=mx+b.

3x+y=5

     y = -3x + 5  

The slope is -3.

In addition, the slope of two parallel line would be equal, the slope of the line would be -3.

y- y1 = m(x- x1)

y- (-4) = -3(x - -1)

y + 4 = -3(x+1)

Answer:

i hope it will be right

Step-by-step explanation:

it will be 31ْ

Answer:

You got them both right, no other choices need to be selected.

Step-by-step explanation:

Both the choices you have put yes to, will give an answer equal to 32.

Since they want us to find the full amount of students in his class, and 20 is 4 more than half the class 20-4=16 and then 16 x 2 is 32

1/2m+4=20 is correct because, if you move the 4 across the equal sign it become a negative and will be subtracted from the 20 therefore becoming 16. 1/2m=16. Now left with only the 1/2m we must multiply by 2 because 1/2 is a fraction and mutipliting it by 2 will allow us to get 1/2 to equal 1 and m by itself.

1/2m*2=1m

1m=16*2 Keep in mind you must do the same to both sides so the 16 is multiplied as well.

4th option: Same thing different order

Just send 1/2m over equal sign and 4 over the equal sign to trade places. and you will have 1/2m=16

Answer:

A. The answer is 165.85.                                                                                        B. The best answer is 1.435 ·103 because while they both are really small for a rail road track that one is bigger. the final answer for that is 147.805mm.

Step-by-step explanation:

(3.9 x 10³³) / 1  =  X / (2.45 x 10⁵)  .

Solve that proportion for ' X ' in the usual way.

If you can't remember how to solve a proportion, then  

THAT's what you have to go look up.  It's much more

important to you right now than how much energy the  

sun is putting out.

7.4 x 10⁴ mm is the same size as about 243 feet !

If the tracks on a DVD were that far apart, there would not be  

room for very many tracks on a DVD.  That's not reasonable.

If the tracks are  7.4 x 10⁻⁴ mm apart, then there are about  

34,000 tracks in a stripe that's 1-inch wide.  I have no idea

how they do this, but it's certainly more reasonable than the  

other choice.                                                                                                                      Hope this helps! Can you please give me Brainleist?

Answer:

3 is 14 less than 17

Step-by-step explanation:

Given the model:

3 + 14 = 17

Say :

A = 17

B = 3

C = 14

Comparing 3 to 17 in the model :

We can express 17 interms of 3 and 14

3 + 14 = 17

17 is the sum of 3 and 14

Therefore, 17 is 3 greater than 14 or 14 greater than 3

14 = 17 - 3

14 is 3 less than 17

3 = 17 - 14

3 is 14 less than 17

From the options , the correct statement which models the comparison between 17 and 3 is ;

"3 is 14 less than 17".

Answer:

  3.  x = 10

  4.  a = 8

Step-by-step explanation:

A reasonably simple rule to remember for secants outside the circle or chords inside the circle: the product of the lengths from the point of intersection of the lines to the points of intersection of the circle is the same for each line.

When the external line is tangent to the circle, the two points of intersection of the line with the circle are the same: the point of tangency. Effectively, this means the length is squared.

__

3. For line QP, the product is 3(3+5) = 24.

For line QR, the product is 2(2+x). The rule above says these are equal:

  24 = 2(2+x)

  12 = 2+x . . . . . divide by 2

  10 = x . . . . . . . subtract 2

__

4. For line BC, the product is (a)(a) = a^2.

For line GC, the product is 4(12+4) = 64. The rule above says these are equal:

  a^2 = 64

  a = √64 . . . . take the square root

  a = 8

Answer: Second equation should be x/10 = 12/16

Step-by-step explanation:

Everything is right except that x=12 and 10=16

Answer:

x < 11

Step-by-step explanation:

Given

3x + 3 < 36 ( subtract 3 from both sides )

3x < 33 ( divide both sides by 3 )

x < 11

Answer:

  B)  y = (x -7)(4x +3)

Step-by-step explanation:

For zeros p and q, factors of the function are (x -p) and (x -q).

For the given zeros, the factors are (x -7) and (x -(-3/4)). By multiplying the latter by 4, we can eliminate the fraction.

  y = (x -7)(4x +3)

Answer:

6,6

Step-by-step explanation:not right sorry

Answer:

1) There are 100 carbon-14 atoms in the wood when it died

2) A function that models the number 'N' of carbon-14 atoms present in the wood (t) years after it died is  presented as follows;

[tex]N = 100 \times \left (\dfrac{1}{2} \right )^{\dfrac{t}{5,730} }[/tex]

Step-by-step explanation:

The given parameters are;

The number of carbon-12 for each carbon-14 atom ≈ 10¹² carbon-12 atoms

The number of carbon-12 in the piece of wood = 10¹⁴ carbon-12 atoms

The number of carbon-14 in the piece of wood = 40 carbon-14 atoms

The number of carbon-12 in an organism = Constant

The number of carbon-14 in an organism = Decays

1) Given that the number of carbon-12 in an organism is constant, and there are 10¹² carbon-12 atoms per each carbon-14 atom, therefore, we have;

The number of carbon-12 atoms in the wood when it died = 10¹⁴ carbon-12 atoms

The number of carbon-14 atoms in the wood when it died = (10¹⁴ carbon-12 atoms)/(10¹² carbon-12 atoms/(carbon-14 atom)) = 100 carbon-14 atoms

The number of carbon-14 atoms in the wood when it died = 100 carbon-14 atoms

2) The half life of a radioactive isotope is given by the following formula;

[tex]N(t) = N_0 \cdot \left (\dfrac{1}{2} \right )^{\dfrac{t}{t_{\frac{1}{2} }} }[/tex]

The half life of carbon-14 atoms, [tex]t_{\frac{1}{2} }[/tex] ≈ 5,730 years

N₀ = The amount of carbon-14 present in the wood when it died = 100 carbon-14 atoms

Therefore, we have;

The number, N, of carbon-14 atoms present in the wood (t) years after it died is given as follows;

[tex]N = 100 \times \left (\dfrac{1}{2} \right )^{\dfrac{t}{5,730} }[/tex]
