Answer:
u = -7/4
Step-by-step explanation:
This is correct because to find the perpendicular, you need to find the opposite reciprocal of the slope. In this case, the slope is 4/7, so the opposite reciprocal is -7/4.
Answer:
[tex]\displaystyle m_u=-\frac{7}{4}[/tex]
Step-by-step explanation:
Perpendicular Lines
If two lines t and u are perpendicular and have slopes mt and mu respectively, then the following relationship is satisfied:
[tex]m_t\cdot m_u=-1[/tex]
Knowing line t has a slope of \frac{4}{7}, then the slope of line u can be found by solving for mu:
[tex]\displaystyle m_u=-\frac{1}{m_t}[/tex]
[tex]\displaystyle m_u=-\frac{1}{\frac{4}{7}}[/tex]
Operating:
[tex]\mathbf{\displaystyle m_u=-\frac{7}{4}}[/tex]

Step-by-step explanation:
Considerando que cada semana se van acumulando los amigos de la semana anterior. ¿Cuántos amigos se fueron uniendo por semana ? Suponiendo que cada semana fueran nuevos amigos cuántos tendría en total? En este mismo supuesto ¿En qué semana alcanzara más de la mitad de Seguidores que acumulo en las doce semanas?
Answers
Answer:
1. Amigos nuevos cada semana: 7, 8, 4, 4, 5, 4, 3, 5, 8, 2, 7, 7
2. 418 amigos en total.
3. En la Semana 9 se alcanzan 247 amigos.
Step-by-step explanation:
He agregado una imagen adjunta con la tabla de datos necesarios para esta pregunta. En la misma se indican la cantidad de amigos o seguidores para cada semana, de un perfil de una red social hipotética.
1. Considerando que cada semana se van acumulando los amigos de la semana anterior. ¿Cuántos amigos se fueron uniendo por semana.
En este caso indica que los amigos se van acumulando cada semana, por lo que la tabla indica los amigos totales del perfil. Para saber cuantos se han agregado cada semana, debemos restar el valor de una semana dada con el valor de la semana anterior. Por ejemplo para la semana 1 indica 7 amigos y para la semana 2 indica 15 amigos, la cantidad de amigos nuevos en la semana 2 es:
semana2 - semana1 = 15 - 7 = 8 nuevos amigos
Los resultados para las semanas 1 a la 12 son:
7, 8, 4, 4, 5, 4, 3, 5, 8, 2, 7, 7
En el archivo excel adjunto (resultados.xlsx) se indican todos los resultados para las 12 semanas.
2. Suponiendo que cada semana fueran nuevos amigos ¿Cuántos tendría en total?
En este supuesto, la tabla de datos indica la cantidad de nuevos amigos cada semana, por lo que para calcular cuantos amigos tendrá en total luego de las 12 semanas se deben sumar todos los valores:
semana1 + semana2 + semana3 +...+...+semana12 = 418 amigos en total
3. En este mismo supuesto ¿En qué semana alcanzara más de la mitad de Seguidores que acumulo en las doce semanas?
Con el mismo supuesto anterior, primero debemos calcular la mitad de amigos totales que alcanzará. Ya hemos calculado que tendrá 418 amigos, por lo que la mitad será:
418÷2 = 209 amigos
Ahora debemos ir sumando los amigos semana a semana, hasta alcanzar un valor igual o mayor a la mitad (209). Eso nos indicará en que semana se supera mas de la mitad de seguidores. Haciendo la operación:
semana1+semana2+semana3+...+...
encontramos que en la semana 9 se alcanzan 247 amigos, superando la mitad calculada anteriormente.
Se pueden ver los detalles en el archivo adjunto resultados.xlsx

Need help it’s writing linear equations!!
Answers
Answer:
the Slope is -6/5 and y is (0,-3)
Step-by-step explanation:
we need to put this equation in y = mx + b
6x - 5y = -15 u will subtract 6x from both sides
5y = -6x -15...divide both sides by 5
and then simplify
y = -6/5x - 3
and when u graph its will be (0,-3)
ur slope(m) = -6/5 and ur y int (b) = -3
2x+3y=15
x+y=6
work out the value of x and y

Multiply second equation by 2
2x + 2y = 12
2x + 3y = 15
Subtract both
-1y = -3, y = 3
Plug in 3 for y in any equation
x + 3 = 6, x = 3
Final answer: x = 3, y = 3
Answer: x=3, y-3
Step-by-step explanation:
I would use elimination
Multiply second equation by 2
2x + 2y = 12
2x + 3y = 15
Subtract both
-1y = -3, y = 3
Plug in 3 for y in any equation
x + 3 = 6, x = 3
Final answer: x = 3, y = 3
