Answer:

A: What is the product of 1 1/2 and −1 1/4?

1\frac{1}{2}=\frac{3}{2}

-1\frac{1}{4}=\frac{-5}{4}

Product will be : \frac{3}{2} \times\frac{-5}{4}

= \frac{-15}{8} or -1\frac{7}{8}

B: What is the product of −2 1/4 and −4 1/2?

-2\frac{1}{4}=\frac{-9}{4}

-4\frac{1}{2}=\frac{-9}{2}

Product will be : \frac{-9}{4} \times\frac{-9}{2}

= \frac{81}{8} or 10\frac{1}{8}

First substitute y=5x+7 so that would turn into 5x+7=6x

Then, isolate/solve for x for 5x + 7 = 6x, in this problem x=7

Substitute x=7 into y=5x+7

y=42


x=7, y=42

Kiara desea contratar el servicio de una línea telefónica con internet para realizar sus clases virtuales. Si el costo de una lí
ArbitrLikvidat [17]

a) Kiara ha adquirido una línea de telefonía móvil con internet a un Coste Fijo de 10 soles y un Tasa de Consumo de 1,5 soles por hora consumida.

b) El Coste total por 48 horas de consumo de la línea telefónica con internet es 82 soles.

a) Nota - Puesto que la ecuación que describe el Coste ya existe en el enunciado, entonces se entiende el verbo <em>"Expresa"</em> como <em>"Describa en sus propias palabras"</em>.

Como puede apreciarse el Coste de la línea telefónica móvil aumenta linealmente con el Tiempo de consumo por parte del usuario. En consecuencia, la función de Coste queda definida como sigue:

C(t) = C_{o} + r\cdot t (1)

Donde:

  • C_{o} - Coste fijo, en soles.
  • r - Tasa de consumo, en soles por hora.

Entonces, tenemos que Kiara ha adquirido una línea de telefonía móvil con internet a un Coste Fijo de 10 soles y un Tasa de Consumo de 1,5 soles por hora consumida.

b) Una característica de las Funciones Lineales es que tanto su Dominio como Rango comprenden al Conjunto de todos los Números Reales, al ser de Pendiente constante esta Función.

Por tanto, el Dominio y el Rango de la Función en cuestión es el Conjunto de todos los Números Reales.

c) Si sabemos que C_{o} = 10, r = 1,5 y t = 48, entonces el Coste Total por concepto de 48 horas de consumo es:

C(48) = 10 + 1,5\cdot (48)

C(48) = 82

El Coste total por 48 horas de consumo de la línea telefónica con internet es 82 soles.

The air pressure inside Jason’s bike tires decreases by about 6% each week. The original pressure was 45 pounds per square inch
Brrunno [24]
Compound percentage reduction can be calculated by multiplying the initial number by (1-x)^t where x is the percentage reduction (/100, i.e. 1% reduction is 0.01), and t is the number of times it has reduced.

So:
a) p=45(1-0.06)^t=45*0.94^t
Where t is the number of weeks.

We can then just substitute in to work out the final pressure:
b) p = 45*0.94^6 = 31psi
