What is the inverse function of f(x) = x/x-2

Answer:

y = 2*x + 4

Step-by-step explanation:

We know that a linear function can be written as:

y = a*x + b

Where a is the slope and b is the y-intercept.

We know that if this line passes through the points (x₁, y₁) and (x₂, y₂) the slope can be written as:

a = (y₂ - y₁)/(x₂ - x₁)

So, here we know that our line must pass through the points (-2,0) and (0, 4)

Then the slope of this line is:

a = (4 - 0)/(0 - (-2))

a = 4/2 = 2

Then our line is something like:

y = 2*x + b

Now, to find the value of b we can use one of these two points, for example if we use the point (-2, 0), we know that, when x = -2, we must have y = 0.

0 = 2*(-2) + b

0 = -4 + b

4 = b

Then the equation for our line is:

y = 2*x + 4

Answer:

x =33.48537662

Step-by-step explanation:

Since this is a right triangle, we can use trig functions

sin theta = opp/ hyp

sin x = 32/58

Taking the inverse sin of each side

sin^-1 (sin x)  = sin ^-1( 32/58)

x =sin ^-1( 32/58)

x =33.48537662

Answer:

33.47 degrees

Step-by-step explanation:

sin=32/58

sin^-1(32/58)= 33.47

Answer:

x =-8424

Step-by-step explanation:

x÷36= -234

Multiply each side by 36

x÷36  *36 = -234 *26

x =-8424

Answer:

x = -8424

Step-by-step explanation:

[tex]x \div 36 = -234\\\\\frac{x}{36} = -234\\\\x = -234 \times 36 = -8424[/tex]

Answer:

4/11 of 2 1/2 = 4/11 * 5/2 = 20 / 22 = 10/11

a common denominator of 11 and 4 is 44

So 40 / 44 - 33 / 44 = 7/44

Check 4/11 * 2.5 = .909

3/4 = .75    

difference = .909 - .750 = .159

7/44 = .159

Answer:

[tex]y-9=17(x+7)[/tex]

Step-by-step explanation:

Hi there!

What we know:

What we need to know:

Our equation so far (plugging in the point (-7,9):

[tex]y-9=m(x-(-7))[/tex]

[tex]y-9=m(x+7)[/tex]

Determine the slope (m)

[tex]m=\frac{y_2-y_1}{x_2-x_1}[/tex] where two points are [tex](x_1,y_1)[/tex] and [tex](x_2,y_2)[/tex]

Plug in the given points (-8,-8) and (-7,9)

[tex]=\frac{-8-9}{-8-(-7)}\\=\frac{-8-9}{-8+7}\\=\frac{-17}{-1}\\= 17[/tex]

Therefore, the slope of the line is 17. Plug this into [tex]y-9=m(x+7)[/tex]:

[tex]y-9=17(x+7)[/tex]

I hope this helps!

Answer:

x -12 = 7x

x = -2

Step-by-step explanation:

Let the number be x

12 less than the number is:

x -12

equals the product of 7 and that number (7 * x)

x -12 = 7x

7x - x = -12

6x = -12

x = -12/6

x = -2

Answer:

Price of one 25'-tape measure = $11

Price of one chalk line reels = $6

Step-by-step explanation:

Let t = price of one 25'-tape measure, and

let c = price of one chalk line reel

"Shelly purchased 6 25'-tape measures and 2 chalk line reels for $78."

6t + 2c = 78

"Sean purchased one 25'-tape measure and 3 chalk line reels ... for $29."

t + 3c = 29

We have a system of two equations in two variables. We will solve it with teh substitution method.

Solve the second equation for t.

t = 29 - 3c

Substitute 29 - 3c for t in the first equation.

6(29 - 3c) + 2c = 78

174 - 18c + 2c = 78

-16c = -96

c = 6

Substitute 6 for c in the second original equation.

t + 3(6) = 29

t + 18 = 29

t = 11

Answer:

Price of one 25'-tape measure = $11

Price of one chalk line reel = $6

Answer: Hello your question lacks some details attached below is the complete question

answer:

Step-by-step explanation:

The steps required to draw an arc intersecting the line that will create a segment with length PQ are ;

Place a compass at point Q ,  measure arc PQ

Draw an arc with the compass that is equal to PQ ,  Place the compass at point R ,   cut through the line to the left of R with the arc in compass,

Assume the new points to be P' and R be Q' ,   where P' Q' will become the new image of PQ with their end point will be R

Answer:

Set the compass width to the length PQ by putting one end on P and the other and on Q

Without changing the width, move the compass so one end is on R and the other end is on the line containing R

Draw an arc across the line using R as the center

Mark the point where the arc crosses the line as point S

RS is the copied segment.

Answer:

x = 25.7

Step-by-step explanation:

We know the adjacent side to the angle and the hypotenuse on a right triangle

cos theta = adj / hyp

cos 18 = x/27

27 cos 18 =x

25.67852594=x

Rounding to the nearest tenth

x = 25.7

Answer:

Improper fraction: 39/34

Proper fraction: 1 5/34

Decimal: 1.147 (rounded to the nearest thousandths).

Step-by-step explanation:

Solve each expression given, if it has the same result, then the expressions is equivalent. Solve the given expression:

4 7/8 ÷ 4 1/4

First, change all fractions into improper fractions:

4 7/8 = (4 * 8)/8 + 7/8 = 32/8 + 7/8 = 39/8

4 1/4 = (4 * 4)/4  + 1/4 = 16/4 + 1/4 = 17/4

Next, find common denominators. Note that what you do to the denominator, you must do the numerator:

(17/4) * (2/2) = (34/8)

39/8 ÷ 17/4

Solve. First, change the division sign into multiplication, and then flip the second fraction:

39/8 ÷ 17/4 = 39/8 x 4/17

Multiply straight across:

39/8 x 4/17 = (39 x 4)/(8 x 17) = 156/136 = 39/34 (simplified), or 1 5/34.

Answer:

AB = 8.66 m

Step-by-step explanation:

Here, we want to get the length AB

What we have is a right triangle

so to get the length AB, we are going to use the appropriate trigonometric ratio

From the question, AB faces the given angle and that makes it the opposite

AC faces the right angle and that makes it the hypotenuse

The relationship between the hypotenuse and the opposite can be defined by the sine

the sine of an angle is the ratio of the length of the opposite to the hypotenuse

so, we have it that;

sine 60 = AB/10

AB = 10 * sine 60

AB = 8.66 m

Answer:

Sabemos que el costo del alquiler es 100 pesos diarios, más 0.30 pesos por kilómetro.

Entonces, solo por alquilar el coche por un día, hay que pagar 100 pesos.

Si además lo conduces x kilómetros, tendrás que pagar x veces 0.30 pesos.

Entonces el costo diario, en pesos, será:

C(x) = 100 + 0.30*x

Para graficar esta ecuación simplemente se deben encontrar dos pares:

(x, C(x)) en un eje de coordenadas, y luego conectarlos con una línea.

Por ejemplo, si tomamos:

x = 0

C(0) = 100 + 0.30*0 = 100

entonces tenemos el par (0, 100)

si x = 10

c(10) = 100 + 0.30*10 = 100 + 3 = 103

entonces tenemos el par (10, 103)

Ahora podemos graficar esos dos puntos y conectarlos con una línea, como en el ejemplo de abajo.

b)  

También queremos conocer el costo diario si se han hecho un total de 300km.

Entonces simplemente reemplazamos x por 300 en la ecuación del costo:

C(300) = 100 + 0.30*300 = 100 + 90 = 190

El costo será de 190 pesos.

El dinero total a pagar por 300 Km es de 190 pesos.

La ecuación de una recta viene dada por y = mx + c

m = pendiente

c = intersección

Así, dado que cobran 100 pesos por día más 0,30 centavos por kilómetro, podemos escribir;

y = 100 + 0,30 x

Dado también que hay un total de 300 km, ahora tenemos;

y = 100 + 0.3(300) = 190 pesos
