¿Para cuál(es) valor(es) de p las rectas de ecuación x − 1/p = 2 − y/p y x − 1/1 − p = y − 2/2 son perpendiculares? A) Solo para
Akimi4 [234]

Respuesta:

C) Solo para el -1

Explicación paso a paso:

Para resolver este problema, debemos de determinar la pendiente en cada una de las ecuaciones provistas:

\frac{x-2}{p}=\frac{2-y}{p}

y

\frac{x-1}{1-p}=\frac{y-2}{2}

ahora bien, necesitamos conocer el valor de la pendiente de una de las dos ecuaciones. Tomemos la primera ecuación y resolvámosla para y:

\frac{x-2}{p}=\frac{2-y}{p}

Multiplicamos ambos lados para p y obtenemos:

x-1=2-y

volteamos la ecuación y nos da:

2-y=x-1

pasamos el 2 a restar al otro lado y nos da:

-y=x-1-2

-y=x-3

y dividimos ambos lados de la ecuación dentro de -1

y=-x+3

esta ecuación ya tiene la forma pendiente intercepto:

y=mx+b

donde m es nuestra pendiente:

m_{1}=-1

Esta es la pendiente de una de las dos ecuaciones, para que la segunda ecuación sea perpendicular a la primera, su pendiente debe de ser el recíproco negativo de la pendiente de la primera ecuación, entonces la pendiente de la segunda ecuación debe ser:

m_{2}=-\frac{1}{m_{1}}

m_{2}=-\frac{1}{-1}

m_{2}=1

ahora tomamos la segunda ecuación y encontramos su pendiente. Tomemos la ecuación:

\frac{x-1}{1-p}=\frac{y-2}{2}

y despejemos y, comenzamos multiplicando ambos lados de la ecuación por 2, así que obtenemos:

2\frac{x-1}{1-p}=y-2

Multiplicamos el 2 por cada término de la fracción, entonces obtenemos:

\frac{2x-2}{1-p}=y-2

ahora pasamos el 2 a sumar al lado izquierdo y obtenemos:

\frac{2x-2}{1-p}+2=y

Ahora podemos separar la fracción del lado izquierdo en dos fracciones para obtener:

\frac{2x}{1-p}-\frac{2}{1-p}+2=y

volteamos la ecuación y nos da:

y=\frac{2x}{1-p}-\frac{2}{1-p}+2

Ahora nuestra ecuación ya tiene la forma y=mx+b

de aquí podemos determinar nuestra pendiente:

m=\frac{2}{1-p}

Con la primera ecuación determinamos que esta pendiente debería de ser igual a 1, entonces igualamos esa segunda pendiente a 1 para obtener:

\frac{2}{1-p}=1

y despejamos p

Pasamos a multiplicat el 1-p al lado derecho de la ecuación para obtener:

2=1-p

volteamos la ecuación:

1-p=2

pasamos el 1 a restar al lado derecho:

-p=2-1

-p=1

y multiplicamos ambos lados de la ecuación por -1 para obtener:

p=-1

Entonces la respuesta es C) solo para el -1

The system of equations kx-5y = 2, 6x+2y = 7 has no solution, then k =
hoa [83]

Answer:

(d) -15

Step-by-step explanation:

Given system of equations are:

\begin{cases}kx-5y=2\\\\6x+2y=7\end{cases}

Since, given system of equations have no solution.

\therefore \frac{k}{6}=\frac{-5}{2} \neq\frac{2}{7}

\implies \frac{k}{6}=\frac{-5}{2}

\implies k=\frac{6(-5)}{2}

\implies k=\frac{-30}{2}

\implies k=-15

Willow poured the same amount of water into 8 flower pots. She used 5 gallons of water. How much water did each flower get?
larisa86 [58]

Answer:

0.625 gallons each

Step-by-step explanation:

Because she used 5 gallons of water, and poured the same amount of water for each plant, divide the number of gallons she used by the number of plants:

5 divided by 8

= 0.625 gallons per plant

I WILL AWARD BRAINLIEST!
antoniya [11.8K]

Answer:

together they have 60

Step-by-step explanation:

B= number of balloons billy has

A =adams balloons

 Adam had 30 less balloons than Billy

A = B-30  

After Billy gave 5 balloons to Adam, the number of Adam's balloons was half of the number of Billy's balloons.

1/2(B-5) = A+5

1/2 (B-5)-5 =A

set the two equations equal A = B-30    equal to  1/2(B-5)-5 = A


B-30 =  1/2(B-5)-5

add 5 to each side

B-30 + 5 = 1/2 (B-5)

B - 25 = 1/2 ( B-5)

multiply by 2

2(B-25) = 2* 1/2 (B-5)

distribute

2B-50 = B-5

subtract B

2B-50 -B =B-B -5

B-50 = -5

add 50

B-50+50 = -5+50

B = 45

Now we need to find out A

A = B-30

A = 45-30

A = 15

Billy has 45

Adam has 15

together they have 45+15

together they have 60
