-16x+36= 2x

-16x - 2x = -36

-18x = -36

x = 2

Answer:

x = 2

-4 (4(2)-9)=2x

-4 (8-9) = 2x

-4 (-1) = 2x

4 = 2x

Step-by-step explanation:

450.50 - 217.45 = $233.05 :)

The cost of another TV is $677.95

The unitary technique involves first determining the value of a single unit, followed by the value of the necessary number of units.

For example, Let's say Ram spends 36 Rs. for a dozen (12) bananas.

12 bananas will set you back 36 Rs. 1 banana costs 36 x 12 = 3 Rupees.

As a result, one banana costs three rupees. Let's say we need to calculate the price of 15 bananas.

This may be done as follows: 15 bananas cost 3 rupees each; 15 units cost 45 rupees.

Given:

The difference in the price of 2 TVs is $217.45.

One TV costs = $450.5

So, 450 -  Another Tv Cost = 217.45

Another Tv Cost = 217.45+ 450.5

Another Tv Cost = $677.95

Hence, the cost of another TV is $677.95

Answer:

f(x)=x^2-6x-27

Step-by-step explanation:

x=9 and x-3

set the equal to zero: x-9=0 and x+3=0

x-9 and x+3 are now the factors of your equation:

you equation so far is: (x-9)(x+3)=0

next factor these together to get: f(x)=x^2+3x-9x-27

finally simplify the equation leaving you with f(x)=x^2-6x-27

Answer: 9p; 54 books

Step-by-step explanation:

Answer:

x = ± 4

y = - 2

Step-by-step explanation:

y = 0.5x² - 10 ------------------------(I)

y = -x² + 14   ------------------------(II)

Substitute the y value in equation (II)

    0.5x² - 10  = -x² + 14           {Add x² to both sides}            

0.5x² + x² -10 = 14                  {combine like terms}

       1.5x² - 10 = 14                   {Add 10 to both sides}

               1.5x² = 14 + 10

                1.5x² = 24         {Divide both sides by 1.5}

               1.5x²/1.5 = 24/1.5

                       x² = 16

                      x = ±4

Substitute x = 4 in (I)

y = 0.5 * 4² - 10

 = 0.5*16 - 10

 = 8- 10

y = -2

Substitute x = -4 in (I)

y = 0.5 * (-4)² - 10

 = 0.5*16 - 10

 = 8- 10

y = -2

Explicación paso a paso:

Cantidad total de USB comprado = 100

Precio al por mayor = $ 92

Costo de 100 memorias USB = 100 * $ 92 = $ 9,200

Si vende cada memoria USB por $ 100 cada una a precio minorista, la cantidad total en 100 USB será;

100 * $ 100 = $ 10,000

% beneficio = beneficio / precio de coste * 100%

Beneficio = precio de venta - precio de costo

Beneficio = $ 10,000 - $ 9,200

Beneficio = $ 800

% de beneficio = 800/9200 * 100

% de beneficio = 800/92

% beneficio = 8,696%

De ahí que el porcentaje de beneficio que obtiene felipe por cada venta de cada recuerdo es del 8,696%

The table below shows the number of hits for 25 and 50 repetitions.

Answer and Step-by-step explanation: Expected Value or Mean of a probability distribution is calculated as:

E(X) = μ = ∑xP(X)

In a game for the 2012 baseball season, expected value is:

[tex]\mu=0(0.1670)+1(0.3320)+2(0.2864)+3(0.1499)+4(0.0381)+5(0.0266)[/tex]

μ = 1.640

Standard Deviation (σ) of a probability distribution is:

[tex]\sigma=\sqrt{\Sigma (x-\mu)^{2}P(X)}[/tex]

[tex]\sigma = \sqrt{(0-1.640)^{2}(0.1670)+...+(5-1.640)^{2}(0.0266)}[/tex]

σ = 1.1883

The simulate experiment of 25 repetitions shows a table. With this table, it is possible to create a frequency table as follows:

x    |    f

0   |    4

1    |    7

2   |   11

3   |   2

4   |    1

With a frequency table, expected value is calculated as:

[tex]\mu=\frac{\Sigma (fx)}{\Sigma f}[/tex]

[tex]\mu=\frac{0*4+1*7+2*11+3*2+4*1}{25}[/tex]

μ = 1.56

Standard deviation, using a frequency table, is calculated as:

[tex]\sigma = \sqrt{\frac{n\Sigma (fx^{2})-(\Sigma fx)^{2}}{n(n-1)} }[/tex]

[tex]\sigma=\sqrt{\frac{25(0*4^{2}+...+4*1^{2})-(0*4+...+4*1)^{2}}{25(24)} }[/tex]

σ = 0.983

The same can be done for 50 repetitions.

The frequency table is

x      |      f

0     |      6

1      |     18

2     |     16

3     |     9

4     |     1

[tex]\mu=\frac{0*6+1*18+2*16+3*9+4*1}{50}[/tex]

μ = 1.62

[tex]\sigma=\sqrt{\frac{50(0*6^{2}+...+4*1^{2})-(0*6+...4*1)^{2}}{50(49)} }[/tex]

σ = 0.9775

Comparing expected values and standard deviations, observe that the bigger the repetition of the experiment, mean and standard deviation get closer to the theoretical statistical values. This is an example of the Law of Large Numbers, a theorem stating as the number of random, normally distributed values increase, their sample mean approaches the theoretical mean.

Answer:

y = 1, x = 0

Step-by-step explanation:

multiply -4x +9y = 9 by -2 to get 8x -18y = -18

combine the two equations to get -8y = -8

divide both sides by -8 to get y = 1

plug in 1 as the y into one of the equations and solve to get x = 0

Answer:

(0,1)

x = 0

y = 1

Step-by-step explanation:

(-4x + 9y = 9)-8

(-8x + 10y = 10)4

32x - 72y = -72

-32x + 40y = 40

-32y = -32

y= -32/-32

y=1

-4x + 9(1) = 9

-4x + 9 = 9

-4x = -9 + 9

-4x = 0

x = 0/-4

x = 0
