Find f-1(x) if f(x) = 2x/3-4
Given:
The function is:
[tex]f(x)=\dfrac{2x}{3}-4[/tex]
To find:
The inverse of the given function, i.e., [tex]f^{-1}(x)[/tex].
Solution:
We have,
[tex]f(x)=\dfrac{2x}{3}-4[/tex]
Step 1: Substitute [tex]f(x)=y[/tex].
[tex]y=\dfrac{2x}{3}-4[/tex]
Step 2: Interchange x and y.
[tex]x=\dfrac{2y}{3}-4[/tex]
Step 3: Isolate y.
[tex]x+4=\dfrac{2y}{3}[/tex]
[tex]3(x+4)=2y[/tex]
[tex]\dfrac{3x+12}{2}=y[/tex]
[tex]\dfrac{3}{2}x+6=y[/tex]
Step 4: Substitute [tex]y=f^{-1}(x)[/tex].
[tex]f^{-1}(x)=\dfrac{3}{2}x+6[/tex]
Therefore, the inverse of the given function is [tex]f^{-1}(x)=\dfrac{3}{2}x+6[/tex].

If there was only one government class, and Wes and Maureen were in that class of 38 students, what would be the probability that both Wes and Maureen would be selected as the two students to go to Washington? Is this still an example of independent events
The probability of an event is 1/19. Therefore, the given situation is not an independent event.
Given that, Wes and Maureen were in the government class of 38 students.
What is the probability?Probability can be defined as the ratio of the number of favourable outcomes to the total number of outcomes of an event.
We know that, probability of an event = Number of favourable outcomes/Total number of outcomes
Total number of outcomes =38
Number of favourable outcomes = 2
So, probability =2/38
= 1/19
Two events are independent if the occurrence of one event does not affect the chances of the occurrence of the other event.
The probability of an event is 1/19. Therefore, the given situation is not an independent event.

The value of -4 5/8 - x is positive. What are two possible values of x?
Answer:
-6, -7
Step-by-step explanation:
basically
-4 5/8 - x >0
so
x< -4 5/8
you just need 2 values less than -4 5/8
like -6 and -7
The possible values of x could be x = -20 or x = -10 that satisfy the inequality.
Given: -4 5/8 - x > 0
To find two possible values of x that make the expression -4 5/8 - x positive, set up an equation and solve for x.
First, let's convert -4 5/8 to an improper fraction.
The improper fraction equivalent of -4 5/8 is -37/8.
So, -37/8 - x > 0
To isolate x, move -37/8 to the other side of the inequality by adding it to both sides:
x < -37/8
Now, Two possible values of x could be:
x = -20 or x = -10
Both of these values are less than -37/8, so they satisfy the inequality and make the expression -4 5/8 - x positive.

Un alumno multiplica un número por 32 en lugar de multiplicarlo por 23, obteniendo un producto mayor en 54 al producto original. Halla la suma de cifras del producto original
Answer:
La suma de cifras del producto original es igual a 12.
Step-by-step explanation:
De acuerdo a la información proporcionada, si multiplicas un número "x" por 32 su resultado sería igual al producto original "y" más 54 dado que dice que se obtiene un producto mayor en 54 al producto original, lo que se puede expresar de la siguiente forma:
32x=y+54
Además, se puede inferir a partir del enunciado que si el número x se hubiera multiplicado por 23 el resultado habría sido el producto original que lo denominamos como "y", por lo que puedes decir que:
y=23x
Ahora puedes reemplazar y=23x en 32x=y+54 y despejar x:
32x=23x+54
32x-23x=54
9x=54
x=54/9
x=6
Finalmente, puedes reemplazar el valor de x en y=23x:
y=23x
y=23*6
y=138

F(x)=400-4/5x find the function and intercepts
Answer:
The x-intercept is (500, 0); the y-intercept is (0, 400).
Step-by-step explanation:
F(x)=400-4/5x is already a function: a function of x.
To find the y-intercept, set x = 0 and calculate F(0):
F(0) = 400 - 0 = 400; the y-intercept is (0, 400).
To find the x-intercept, set F(x) = y = 0 and solve for x:
0 = F(x) = 400 - (4/5)x, or (4/5)x = 400. To isolate x, multiply both
sides by (5/4): x = (5/4)(400) = 500. The x-intercept is (500, 0).

Answer:
11.75
Step-by-step explanation:
All angles of a right triangle equal 180°.
So you have to do a substitution method to find the value of x.
Which leaves us with: angle 'A' = 5 × 11.75, angle 'B' = ((3 × 11.75) -4), and angle 'C' = 90. If you add all of them together it is equivalent to 180°.
∴ x = 11.75

Answer:
35
Step-by-step explanation:
Create a proportion where x is the number of Warrior fans
[tex]\frac{5}{3}[/tex] = [tex]\frac{x}{21}[/tex]
Cross multiply and solve for x
105 = 3x
35 = x
So, there were 35 Warrior fans
Answer:
[tex] \bf\huge warrior \: fans = 35[/tex]
Step-by-step explanation:
Given that :The ratio of Warrior fans to Laker fans at a basketball game was 5 to 3.If there were 21 Laker fans.to find :how many Warrior fans are there.let us assume :warrior fans is X .explanation :finding the warrior fans
⟼ warrior : laker fans = 5 : 3 = x : 21
⟼ 5 : 3 = x : 21
⟼ [tex]\frac{5}{3} \times \frac{x}{21} [/tex]
⟼ x = 5 × 7
⟼ x = 35.
⟼ warriors fans = 35.
∴ laker fans is 21 and warriors fan is 35.
∴ warriors : laker fans = 5 : 3 = 35:21.

Solution given:
Initial point = -50 ft
Climbing rate = 15 ft/min
Time = t(let)
So Required inequality:
15t-50 > 5
adding 50 on both term
15t> 55
dividing both term by 15
t > 55/15

How much larger is 6 x 10^5 compared to
2 x 10^3?Explain how you know.
Answer:
6 x 10^5 is 300 times greater than 2 x 10^3.
Step-by-step explanation:
Use division to compare.
(6 × 10^5)/(2 × 10^3) = 6/2 × 10^5/10^3 = 3 × 10^2 = 3 × 100 = 300
6 x 10^5 is 300 times greater than 2 x 10^3.
There is 6 × 10⁵ is 300 times greater than 2 × 10³.
What is the Scientific Notation?Scientific Notation is a way of writing down in the easy form of very large or very small numbers.
The exponents are given in the question, as follows:
6 × 10⁵ and 2 × 10³
The exponents in scientific notation as a shorthand for the number of zeroes in the number.
We use division to compare.
( 6 × 10⁵)/(2 × 10³)
= 6/2 × 10⁵/10³
= 3 × 10²
= 3 × 100
= 300
This means 6 × 10⁵ is 300 times greater than 2 × 10³

Six friends attend a music concert and spend $27 per ticket. They each purchase a souvenir t-shirt. If the friends spend a total of $231, how much does each souvenir t-shirt cost
Answer:
11.50
Step-by-step explanation:
6x27=162
231+-162=69
69 divided by 6 is 11.5
11.5=11.50
11.50 is your answer
Answer:
$11.50.
Step-by-step explanation:
If there are 6 friends, and every ticket costs $27, then we need to multiply.
6 x 27 = 162.
Then, we subtract the cost of the tickets so we can find the total cost of the souvenir t-shirts.
231 - 162 = 69.
Since each of the 6 friends bought a souvenir t-shirt, we divide the total cost by the number of people.
[tex]\frac{69}{6}[/tex] = 11.5.
So, each t-shirt costs $11.50.
