Solution

Claro, vamos a resolver cada pregunta paso a paso.

Pregunta 1: Resolver el sistema de ecuaciones: 2x+3y=8 2x + 3y = 8 2y=4 -2y = -4

Primero, resolvemos la segunda ecuación para y y : 2y=4 -2y = -4 y=2 y = 2

Ahora sustituimos y=2 y = 2 en la primera ecuación: 2x+3(2)=8 2x + 3(2) = 8 2x+6=8 2x + 6 = 8 2x=2 2x = 2 x=1 x = 1

La solución del sistema es (1,2) (1, 2) .

Pregunta 2: Graficar el siguiente sistema no lineal de ecuaciones e identificar las dos soluciones: y=x2+6x4 y = x^2 + 6x - 4 y=x+4 y = -x + 4

Igualamos las dos ecuaciones para encontrar los puntos de intersección: x2+6x4=x+4 x^2 + 6x - 4 = -x + 4 x2+7x8=0 x^2 + 7x - 8 = 0

Resolvemos la ecuación cuadrática: x=b±b24ac2a x = \frac{-b \pm \sqrt{b^2 - 4ac}}{2a} x=7±49+322 x = \frac{-7 \pm \sqrt{49 + 32}}{2} x=7±812 x = \frac{-7 \pm \sqrt{81}}{2} x=7±92 x = \frac{-7 \pm 9}{2}

Entonces, x=1 x = 1 y x=8 x = -8 .

Sustituimos estos valores en y=x+4 y = -x + 4 : Para x=1 x = 1 : y=1+4=3 y = -1 + 4 = 3

Para x=8 x = -8 : y=8+4=12 y = 8 + 4 = 12

Las soluciones son (1,3) (1, 3) y (8,12) (-8, 12) .

Pregunta 3: Kofi tiene dos opciones de pago. Plan A es un salario mensual de 700 GHS más una comisión del 15% sobre las ventas mensuales. Plan B es un salario mensual de 800 GHS más una comisión del 6.5% sobre las ventas mensuales. ¿Cuánto tendría que vender Kofi mensualmente para que el Plan A sea la mejor opción?

Sea S S el monto de las ventas mensuales.

Plan A: 700+0.15S 700 + 0.15S

Plan B: 800+0.065S 800 + 0.065S

Queremos que Plan A sea mejor que Plan B: 700+0.15S>800+0.065S 700 + 0.15S > 800 + 0.065S 0.15S0.065S>800700 0.15S - 0.065S > 800 - 700 0.085S>100 0.085S > 100 S>1000.085 S > \frac{100}{0.085} S>1176.47 S > 1176.47

Kofi tendría que vender más de 1176.47 GHS por mes.

Pregunta 4: El Family Community Theatre cobra 7porentradasdeadultosy7 por entradas de adultos y 2 por entradas de niños. La semana pasada se vendieron 738 entradas en total para un ingreso de $3656. ¿Cuántas entradas de cada tipo se vendieron?

Sea a a el número de entradas de adultos y c c el número de entradas de niños.

Sistema de ecuaciones: a+c=738 a + c = 738 7a+2c=3656 7a + 2c = 3656

Resolvemos el sistema: De la primera ecuación: c=738a c = 738 - a

Sustituimos en la segunda ecuación: 7a+2(738a)=3656 7a + 2(738 - a) = 3656 7a+14762a=3656 7a + 1476 - 2a = 3656 5a=2180 5a = 2180 a=436 a = 436

Entonces: c=738436=302 c = 738 - 436 = 302

Se vendieron 436 entradas de adultos y 302 entradas de niños.

Pregunta 5: Determinar si el sistema es "inconsistente", "dependiente" o "independiente": 5x+2y=6 5x + 2y = 6 10x+4y=12 10x + 4y = 12

Multiplicamos la primera ecuación por 2: 10x+4y=12 10x + 4y = 12

Observamos que la segunda ecuación es idéntica a la primera multiplicada por 2, lo que significa que las dos ecuaciones son dependientes.

El sistema es "dependiente".
