Answer:
[tex]y = \frac{2x}{x - 1} [/tex]
Step-by-step explanation:
find the inverse of the function
To find the inverse function, swap x and y, and solve the resulting equation for x.
If the initial function is not one-to-one, then there will be more than one inverse.
So, swap the variables
[tex]y = \frac{x}{x - 2} [/tex]
becomes
[tex]x = \frac{y}{y - 2} [/tex]
Now, solve the equation
[tex]x = \frac{y}{y - 2} [/tex]
for y.
[tex]y = \frac{2x}{x - 1} [/tex]

Answer:
the first one has no solution because the lines never intersect.
the second one has one solution: (-3, 3)
the third one has an infinite solution because there lines are on top of each other the entire time.
Step-by-step explanation:
:)
Step-by-step explanation:
(i) No solution
Because they are parallel to each other
(ii) One solution
Because they intersect each other

(iii) Infinite solution
Because they are in one line
Margaret has some goats. The goats produce an average total of 21.7 litres of milk per day for 280 days. Margaret sells the milk in 12 litre bottles. Work out an estimate for the total number of bottles that Margaret will be able to fill with the milk. You must show clearly how you got your estimate.
Answer:
506 bottles
Step-by-step explanation:
21.7 * 280 = 6076 litters
6076/12 = 506.33333……. = 506 bottles
(0.33333 is less than 0.55555)

At chucky bee restaurant, the meal costs $55.25 and desserts cost $15.75 for 5 people. How much money does each person have to pay?
Answer:
$14.20
Step-by-step explanation:
First we add both the meal ($55.25) and the dessert ($15.75) to calculate the total cost which would be $77.00 Assuming the bill was evenly split among the five people, we would divide the total cost ($77.00) by all 5 people which gives us 14.20 so each person would have to pay $14.20.
hope this helps!
i need help please, this question has been giving me a headache.
Answer:
The first box (upper left corner)
Step-by-step explanation:
Since the y-intercept is 1/4 (you can find this where x = 0), in slope intercept the second number must equal the y-intercept.
Example:
y = 3x + 2 (0,2) is the y-intercept.
Therefore, the second number must equal 1/4 which the first box is correct.
(Negative 1/4 multiplied by -1 equals positive 1/4)

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.

Can anyone help
looks like the answer C. Thousands.
In the number 72,204 the ones, tens, thousand, and ten thousand will be 4,0,2, and 7 respectively.
What are digits?In a positional numeral system, a numerical digit is a single sign that can be used singly or in combination to represent numbers.
A digit is a part of a set that, when combined, makes up a numeration system.
For example 0, 1, 2, 3, 4, 5, 6, 7, 8, 9 are digits.
The place value of a general abcd digit is given by
d = ones
c = tens
b = hundreds
a = thousands
So,
In the given number 72,204
4 = ones
0 = tens
2 = hundreds
2 = thousands
7 = hundred thousand
Hence "In the number 72,204 the ones, tens, thousand, and ten thousand will be 4,0,2, and 7 respectively".

After a dilating a square with a scale factor of 3, which describes the image of the square?
O Its sides are 1/3 as long as those of the original square.
O its sides are 3 times as long as those of the original square.
O Its sides are 3 units longer than those of the original square.
O Its sides are 3 units shorter than those of the original square.
Answer:
2. It's sides are 3 times as long as those of the origanal square.
Step-by-step explanation:
The scale factor is 3. So the scale of the sides of the orig. square to the image is 1:3. So, it is 3 times as large as the preimage.
Hi, I need an answer to this question pls. Louisa used Uber which charges $2 for the first mile and $1.10 for each additional mile. Pietro used Lift which charges $5 for the first mile and $0.95 for each additional mile. They paid the same amount and traveled the same distance. How far did they travel? Show work pls!!
Answer:
20 miles
Step-by-step explanation:
Let x = amount charge each mile
y = total price paid
Since the Uber charged $1.10 for each mile, we multiply x by 1.1 like this 1.1x
Also, $2 were already charged so we add 2 to the total price
y = 1.1x + 2
Since the Lyft charged $0.95 for each mile, we multiply x by 0.95 like this 0.95x
Also, $5 were arleady charged so we add 5 to the total price
y = 0.95x + 5
We have to find a price where both rides match
1.1x + 2 = 0.95x + 5
Let's move the like terms to one side by subtracting 0.95x from both sides
1.1x + 2 = 0.95x + 5
-0.95x -0.95x
0.15x + 2 = 5
Now, subtract 2 from both sides
0.15x + 2 = 5
- 2 - 2
0.15x = 3
Finally, divide both sides by the coefficient, 0.15, to isolate the variable, x
0.15x/0.15 = 3/0.15
x = 20
This means they traveled 20 miles if they were to pay the same price

1/6x-1/8=11/12
Answer:
6 and 1/4
Step-by-step explanation:
1/6 x - 1/8 = 11/12
First, let's find the least common denominator (24) to make these fractions manageable to work with: 4/24 x - 3/24 = 22/24.
Next, add 3/24 to both sides: 4/24 x = 25/24.
We can cancel out the denominators at this point to get: 4x=25.
Divide both side by 4, and x = 25/4 = 6 and 1/4 or 6.25
