Cual de las siguientes expreciones permite a fatima obtener t que es la cantidad de palitos nesesaria para armar una figura n
Likurg_2 [28]

Answer:

T(n) = 4 + 12*n

Step-by-step explanation:

La pregunta completa se puede ver en la imagen de abajo.

En ella, podemos ver que:

La primera figura tiene: 16 palitos

la segunda figura, con n = 2, se añaden 3 palitos en cada extremo, por lo que tendremos 16 palitos + 4*3 palitos = (16 + 12) palitos

De manera similar, en la tercera figura se vuelven a añadir 3 palitos en cada extremo de la cruz, entonces esta figura tendrá:

(16 + 12) palitos + 4*3 palitos = (16 + 12 + 12) palitos.

Así, tenemos la relación:

T(1) = 16

T(2) = 16 + 12

T(3) = 16 + 12 + 12

Podemos asumir que la forma general será:

T(n) = 16 + 12*(n - 1)

podemos reescribir esto como:

T(n) = (12 + 4) + 12*(n - 1)

      = 4 + 12 + 12*(n - 1)

      = 4 + 12*n

La opción correcta es la primera.

Write an equation in slope intercept form of the line that passes through the given point and is parallel to the graph of the gi
kupik [55]

For this case we have that by definition, the equation of a line in the slope-intersection form is given by:

y = mx + b

Where:

m: It is the slope of the line

b: It is the cut-off point with the y axis

We have the following line:

y = 2x-8

The slope is m_ {1} = 2

By definition, if two lines are parallel then their slopes are equal. Thus, a line parallel to the given line will have a slopem_ {2} = 2

Therefore, the equation of the parallel line will be of the form:

y = 2x + b

We substitute the given point and find "b":

3 = 2 (-1) + b\\3 = -2 + b\\3 + 2 = b\\b = 5

Finally, the equation is:

y = 2x + 5

Answer:

y = 2x + 5

If 2x - 3 + 3x equals -28 what is the value of x​
Paul [167]

Chapter : Linear equations

Lesson : Math of Junior High School

2x - 3 + 3x = -28

= 5x - 3 = -28

= 5x = -28 + 3

= 5x = -25

= x = -25 / 5

= x = 5

¼ log b x – 2 log b 5 – 10log b y
melamori03 [73]

I will leave out the base, b since it's the same for all these logarithms.

\frac{1}{4} Log(x)-2Log(5)-10Log(y)  \\  \\ Power-Rule \\  \\ Log( x^{ \frac{1}{4} } )-Log( 5^{2} )-Log( y^{10} ) \\  \\ Quotient-Rule \\  \\ Log( x^{ \frac{1}{4} } ) -Log( \frac{25}{ y^{10} } ) \\  \\ Quotient-Rule \\  \\ Log( \frac{ x^{ \frac{1}{4} }  y^{10} }{25} )
