Well the guy who answered on top is wrong.
But the answer is (D) F-1 (X) = 7x - 3
Step-by-step explanation:
Well took the test and got the answer wrong for the guy on top and took it again and got it right...
The inverse of the function f(x) is equivalent to -
f ⁻¹(x) = 7(3 - x).
What is a mathematical equation and expression?In mathematics, a function from a set X to a set Y assigns to each element of X exactly one element of Y. The set X is called the domain of the function and the set Y is called the codomain of the function.Equation modelling is the process of writing a mathematical verbal expression in the form of a mathematical expression for correct analysis, observations and results of the given problem.A mathematical expression is made up of terms (constants and variables) separated by mathematical operators.A mathematical equation is used to equate two expressions.Given is the function -
f(x) = 3 - x/7
The given function is -
f(x) = 3 - x/7
we can write -
y = 3 - x/7
Replace [y] and [x], as follows -
x = 3 - y/7
y/7 = 3 - x
y = 7(3 - x)
f ⁻¹(x) = 7(3 - x)
Therefore, the inverse of the function f(x) is equivalent to -
f ⁻¹(x) = 7(3 - x).

What’s the answer for 350÷10*3
During a musical an orchestra is playing. As the music plays, the volume changes in the beginning of the piece can be modeled by the equation s = 10│x - 4│+ 50 where s represents the sound level in decibels and x represents the number of measures of music played. Explain in words each step to find the following question:
At what number(s) measures played would the sound level be at 80 decibels?
Hey Child.
The answer to this is 1 or 7:
To find the range for the number of measures played to satisfy our solution, we must solve for x using s = 80.
Next, we subtract 50 from both sides of the equation.
Next, we divide both sides of the equation by 10
Next, to eliminate the absolute value bars, we will add a ± sign in front of our s value, 3.
Finally, we add 4 to both sides of our equation giving us 4 ± 3 = x
Separating this into two equations, we get 4 - 3 = x and 4 + 3 = x
Therefore, x, the number of measures of music played, must be either 1 or 7.

If m\angle CED=101 then what is m\angle CEH∠CEH
Answer:
m∠CEH = 79°
Step-by-step explanation:
From the picture attached,
∠CED and ∠CEH are the pair of linear angles.
Since, pair of linear angles are supplementary angles.
m∠CED + m∠CEH = 180°
101° + m∠CEH = 180°
m∠CEH = 180° - 101°
= 79°
Therefore, measure of angle CEH is 79°.

Linear equation
A line with the slope of 1/2 pass through the point (3,-2)
a) Write the equation of the line in Point - Slope Form.
b) Write the equation of the line in Slope - intercept form.
Answer:
see explanation
Step-by-step explanation:
The equation of a line in point- slope form is
y - b = m(x - a)
where m is the slope and (a, b) a point on the line
Here m = [tex]\frac{1}{2}[/tex] and (a, b) = (3, - 2) , thus
y - (- 2) = [tex]\frac{1}{2}[/tex] (x - 3) , that is
y + 2 = [tex]\frac{1}{2}[/tex]( x - 3) ← in point- slope form
(b)
The equation of a line in slope- intercept form is
y = mx + c ( m is the slope and c the y- intercept )
Here m = [tex]\frac{1}{2}[/tex] , thus
y = [tex]\frac{1}{2}[/tex] x + c ← is the partial equation
To find c substitute (3, - 2) into the partial equation
- 2 = [tex]\frac{3}{2}[/tex] + c ⇒ c = - 2 - [tex]\frac{3}{2}[/tex] = - [tex]\frac{7}{2}[/tex]
y = [tex]\frac{1}{2}[/tex] x - [tex]\frac{7}{2}[/tex] ← in slope- intercept form

Suppose that f(x) = 7x-6 and g(x) = - 4x +5. Solve f(x) = 0
put the value of f(x) = 0
f(0) = 7(0)-6
=0-6
= -6
Step-by-step explanation:
f(x)= 7x - 6
f(x) = 0
7x - 6 = 0
7x = 6
x = 6/7 ? (I think you need to solve for x)

The school that Danielle goes to is selling tickets to a spring musical. On the first day of ticket sales the school sold 10 adult tickets and 13 student tickets for a total of $234. The school took in $97 on the second day by selling 5 adult tickets and 4 student tickets. What is the price each of one adult ticket and one student ticket?
Answer:
Price of Adult tickets =$ 13
Price of student tickets =$ 8
Step-by-step explanation:
Lets us represent the price of adult tickets = x
The price of student tickets = y
On the first day of ticket sales the school sold 10 adult tickets and 13 student tickets for a total of $234.
= 10 × x + 13 × y = $234
= 10x + 13 y = 234
The school took in $97 on the second day by selling 5 adult tickets and 4 student tickets.
5 × x + 4 × y = $97
= 5x + 4y = 97
Hence:
10x + 13y = 234......Equation 1
5x + 4y = 97......... Equation 2
We solve by elimination method
Multiply the equation 1 by 5 and equation 2 by 10 which are the coefficient of x
10x + 13y = 234......Equation 1 × 5
5x + 4y = 97......... Equation 2 × 10
50x + 65y = 1170......Equation 3
50x + 40y = 970..... Equation 4
Subtract Equation 4 from Equation 3
25y = 200
y = 200/25
y = 8
Therefore the price of student ticket = $8
Note that
5x + 4y = 97......... Equation 2
5x + 4 × 8 = 97
5x = 97 + 32
5x = 65
x = 65/5
x = 13
Therefore price of adult tickets = $13

Solve for t: 5t - 4 = 11
Answer:
t = 3
Step-by-step explanation:
5t - 4 = 11
5t - 4 + 4 = 11 + 4 (you do the plus 4 to get rid of the -4 and what you do to one side you have to do to the other.)
5t = 15
5t/5 = 15/5 (To get red of the 5 do reverse operation.)
1t = 3 simplified to
t = 3
Hope it helped (brainlyest pls) ;)
Answer:
3
Step-by-step explanation:
5t - 4 = 11
(5 x t) - 4 = 11

A sprout in Jessie’s garden is 5 1/5 cm tall and is growing 1 3/10 cm each week. Write and solve an equation in order to determine how many weeks it will take for the plant to be 13 cm tall.
It will take 6 weeks for the sprout in Jessi's garden to grow 13 cm tall.
Given that,
A sprout in Jessie’s garden is 5 1/5 cm tall and is growing 1 3/10 cm each week. Write and solve equality in order to resolve how many weeks it will take for the plant to be 13 cm tall is to be determined.
In calculation, it deals with number of procedures according to the statements. There are four major arithmetic operators, addition, subtraction, multiplication, and division,
Here,
Let the number of weeks be x, the height after each week be y
According to the question,
y = 5 1 /5 + 1 3/10 x
y = 26 / 5 + 13 / 10x
Now,
y = 13
13 = 26 / 5 + 13 /10x
13/10x = 13 - 26 / 5
x = 39 × 10 / 5 × 13
x = 3 ×2
x = 6
Thus, it will take 6 weeks for the sprout in Jessi's garden to grow 13 cm tall.

s ≤ 160
This means, S is less than or equal to 160
approximate sqrt 12 to the nearest interger
Answer: 3 is the nearest integer.
Step-by-step explanation:
The square root of 12 is between 3 and 4
9 and 16 are perfect squares. Their roots are 3 & 4 respectively. 12 is about halfway between, so a good approximation would be 3 1/2, but the question asks for the nearest integer, not the nearest rational number.
