y=40/5
y= 8
RS = 9y+3 = 9(8)+3= 72+3=75
ST= 3y+4 = 3(8)+4=24+4=28

Kiara desea contratar el servicio de una línea telefónica con internet para realizar sus clases virtuales. Si el costo de una línea de telefonía móvil con Internet es C = 10 + 1,5t (C, en soles; t, en horas).
- Expresa el costo de la línea telefónica móvil en función del tiempo.
- Determina el dominio y el rango de una función.
- ¿Cuál será el costo luego de 48 horas de consumo de la línea telefónica con Internet?
Doy coronita
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 "Expresa" como "Describa en sus propias palabras".
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:
[tex]C(t) = C_{o} + r\cdot t[/tex] (1)
Donde:
[tex]C_{o}[/tex] - Coste fijo, en soles.[tex]r[/tex] - 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 [tex]C_{o} = 10[/tex], [tex]r = 1,5[/tex] y [tex]t = 48[/tex], entonces el Coste Total por concepto de 48 horas de consumo es:
[tex]C(48) = 10 + 1,5\cdot (48)[/tex]
[tex]C(48) = 82[/tex]
El Coste total por 48 horas de consumo de la línea telefónica con internet es 82 soles.

Find the slope of the line whose equation is 8 y = 4 − 3 x .
Answer:
-3/8
Step-by-step explanation:
8y = 4 - 3x
~Divide 8 to everything
y = 1/2 - 3/8x
~Reorder
y = -3/8x + 1/2
In slope intercept form [ y = mx + b ] m resembles the slope so -3/8 is the slope.

is 4x2
square feet
Which of the following expressions represents the difference between the area of his old
rug and the area of his new rug?

the ratio of zoes money to yolansa's is 3:7. Yolanda has $64 more than Zoe. If Yolanda gives (1)/(4) to zoe what is the new ratio of zoes money to yolanda
New Ratio = 19:21
This deals with ratios, fractions and basic arithmetics'.
The ratio of money of zoe to yolansa's own is 3:7.Thus, the total part for each of them will be;
Zoe; 3/10
Yolansa; 7/10
If the total money they both have is x, then they will have;Zoe; 3x/10
Yolansa; 7x/10
Now,Yolanda has $64 more than Zoe. Thus;[tex]\frac{7x}{10}[/tex] - [tex]\frac{3x}{10}[/tex] = 64
Simplifying this gives;
[tex]\frac{4x}{10}[/tex] = 64
Rearranging gives;
4x = 640
x = 640/4
x = $160
Thus, originally;
Yolanda has [tex]\frac{7}{10}[/tex] × 160 = $112
Zoe has [tex]\frac{3}{10}[/tex] × 160 = $48
Yolanda now gives [tex]\frac{1}{4}[/tex] of her money to Zoe.
Thus, she gives out [tex]\frac{1}{4}[/tex] × 112 = $28
Thus,
Zoe now has; 48 + 28 = $76
Yolanda now has; 112 - 28 = $84
New ratio of zoes money to yolandas money is;76:84
Simplifying this ratio gives;
19:21

We are required to find the new ratio of zoes money to yolanda
the new ratio of zoes money to yolanda is 19:21
Ratio of zoes money to Yolanda's = 3:7.
Zoes = 3
Yolanda = 7
Total ratio = 3 + 7 = 10
let
x = Total money
Zoes = 3/10
Thus, the total part for each of them will be;
Zoe= 3/10x
Yolanda = 7/10x
Yolanda has $64 more than Zoe.
Therefore,
7/10x - 3/10x = 64
(7x - 3x) / 10 = 64
4x/10 = 64
cross product
4x = 64 × 10
4x = 640
divide both sides by 4
x = 640/4
x = $160
Original share:
Zoe = 3/10x
= 3/10 × 160
= 0.3 × 160
= $48
Yolanda = 7/10x
= 7/10 × 160
= 0.7 × 160
= $112
If Yolanda gives 1/4 to zoe
= 1/4 of 112
= 1/4 × 112
= 0.25 × 112
= $28
New Zoe's share = $48 + $28
= $76
New Yolanda's share = $112 - $28
= $84
Their new ratio = 76 : 84
divide by 4
= 19 : 21

two members have a sum of 112. If one number is x, represent the other numbers as an expression in x
Based on the information given, the other number will be 112 - x
Value of the first number = x
Value of the second number = y
Sum of the numbers = 112
Therefore, the value of the second number will be:
x + y = 112
y = 112 - x
In conclusion, the value of the second number is 112 - x.

Suppose PQ has one endpoint at
P(0, 0). If (2,5) is the midpoint of PQ, what are the
coordinates of point Q?
Step-by-step explanation:
The midpoint can be found with the formula.
midpoint = (x1+x2) /2 , (y1 + y2 )/2
( x1 , y1), and (x2 , y2 ) are the coordinates of two points, and the midpoint is a point lying equidistant and between these two points.
P = (0,0)
midpoint = (2,5)
x midpoint = 2 = (0+ x2)/2
×2 = 4
y midpoint = 5 = (y2+0 )/2
10 = y2
so the point Q is (4 , 10)
