Un terreno ha sido cultivado con tres variedades de claveles. La sexta parte ha sido sembrada por
Minchanka [31]

Answer:

1) Se siembra cinco doceavas partes del terreno con claveles rojos y amarillos, 2) Se siembra siete doceavas partes del terreno con claveles blancos.

Step-by-step explanation:

El enunciado se encuentra incompleto. La pregunta faltante es:

2 ¿Qué parte del terreno corresponde a los claveles blancos?

1) Sea A el área total sembrada con los tres tipos de claveles. Entonces, las áreas sembradas con claveles rojos y claveles amarillos son \frac{1}{6}\cdot A y \frac{1}{4} \cdot A, respectivamente.

El área sembrada con claveles rojos y amarillos se obtiene al sumar las áreas correspondientes, es decir:

x = \frac{1}{6}\cdot A + \frac{1}{4}\cdot A

x = \left(\frac{1}{6}+\frac{1}{4}\right)\cdot A

x = \left(\frac{4+6}{24} \right)\cdot A

x = \frac{10}{24}\cdot A

x = \frac{5}{12}\cdot A

Se siembra cinco doceavas partes del terreno con claveles rojos y amarillos.

2) El área sembrada con claveles blancos se obtiene al sustraer el área obtenida en el punto anterior del área total. Esto es:

x = A - \frac{5}{12}\cdot A

x = \left(1-\frac{5}{12} \right)\cdot A

x = \left(\frac{12}{12}-\frac{5}{12}  \right)\cdot A

x = \left(\frac{12-5}{12} \right)\cdot A

x = \frac{7}{12}\cdot A

Se siembra siete doceavas partes del terreno con claveles blancos.

Now evaluate f(x)=2x^4-4x^3-11x^2+3x-6 for x=-2.<br> F(-2)=
neonofarm [45]

Answer:

8

Step-by-step explanation:

f(x)=2x^4-4x^3-11x^2+3x-6

f(-2)=2(-2)^4-4(-2)^3-11(-2)^2+3(-2)-6

f(-2)=2(16)-4(-8)-11(4)-6-6

f(-2)=32+32-44-12

f(-2)=64-44-12

f(-2)=20-12

f(-2)=8

Sophia wrote an equation to represent the revenue of a movie theater for one day. She let x represent the number of child ticket
Angelina_Jolie [31]
The total revenue that is obtained from selling the tickets is the sum of the revenue from selling the child tickets and the adult tickets. If x and y are the number of child and adult ticket, the equation that would represent the given is,
                                   4x + 6y = 420
The equation that would allow us to solve for the number of adult tickets is,
                                        6y = 420 - 4x
Simplifying,
                                         <em>y = 70 - 2x/3</em>
