given that any function of f(x)=x+a/x, where a and can be any value,will have the inverse of the form f^-1(x)=a/x-1
find the inverse of f(x)=x+4/x
please add your working
If f^(-1) is the inverse of f, then
f(f^(-1)(x)) = x
It looks like f(x) = (x + a)/x. This gives us
f(f^(-1)(x)) = (f^(-1)(x) + a)/f^(-1)(x) = x
Solve for f^(-1)(x) :
f^(-1)(x) + a = x f^(-1)(x)
f^(-1)(x) - x f^(-1)(x) = -a
(1 - x) f^(-1)(x) = -a
f^(-1)(x) = -a/(1 - x)
f^(-1)(x) = a/(x - 1)
If a = 4, then the inverse is f^(-1)(x) = 4/(x - 1).
how to understand how to do volumn
Answer:
how tu understand what?
Answer:
To determine a cylinder's volume, you'll need to know its height and the radius of the circular base (the distance between the circle's center and its edge) at both the top and bottom. V = r 2 h is the formula, with V denoting volume, r denoting the radius of the circular base, h denoting height, and pi denoting the constant.

f f(x) and g(x) are inverse functions of each other, which of the following shows the graph of f(g(x))? On a coordinate plane, a straight line has a positive slope and goes through (negative 2, negative 1), (0, 0), and (4, 2). On a coordinate plane, a straight line has a positive slope and goes through (negative 3, negative 3), (0, 0), and (3, 3). On a coordinate plane, a straight line has a negative slope and goes through (negative 4, 2), (0, 0), and (4, negative 2). On a coordinate plane, a straight line has a negative slope and goes through (negative 3, 3), (0, 0), (3, negative 3).
Using inverse function concepts, it is found that the graph of f(g(x)) is given as follows:
On a coordinate plane, a straight line has a positive slope and goes through (-3,-3), (0, 0), and (3, 3).
What happens when two inverse functions are composed?When two functions f(x) and g(x), that are inverse of one another, are composed, that is, y = f(g(x)), the resulting function is given by:
y = x.
Hence the graph of f(g(x)) is given as follows:
On a coordinate plane, a straight line has a positive slope and goes through (-3,-3), (0, 0), and (3, 3).

10. Nine more than three times a number is -6._
a
Answer:
3n + 9 = -6
Step-by-step explanation:
Answer:
Step-by-step explanation:
Let the number = x
3x + 9 = 2x - 6 Looks like you are going to get something negative here.
Subtract 2x from both sides.
3x - 2x + 9 = 2x - 2x - 6
x + 9 = -6
Subtract 9 from both sides.
x + 9 - 9 = - 6 - 9
Combine
x = - 15

Step-by-step explanation:
Answer ASAP. :) Thank you!
Answer:
c = 55
Step-by-step explanation:
I would solve this by cross multiplying, but some teachers don't appreciate you skipping a step like that. Instead:
[tex]\frac{5}{2} =\frac{c}{22}[/tex]
First, multiply both sides by 2:
[tex]5=\frac{2c}{22}[/tex]
Then, multiply both sides by 22:
[tex]2c=110[/tex]
Now, just solve for c by dividing both sides by 2:
[tex]c=55[/tex]
Answer:
C = 55
Step-by-step explanation:
To figure out c you must first isolate c so there shouldn't be any other numbers or signs (addition, subtraction, division, and multiplication) on the same side of the equal sign as variable C.
The inverse of dividing 22 is multiplying 22 on both sides of the equation.
You would get 22/1 * 5/2 = C. 22 * 5 is 110 and 1 * 2 is still 2 so 110/2 = C.
Enter 110/2 into the calculator and you would get C = 55
Find the slope of the line.
Answer:
1
Step-by-step explanation:
it can't be 2 because a slope is always in the mid or after a starting point I think..
Hello there! (:
To find the slope of this graph, we must calculate the rise over the run.
The rise is the amount of units we move up or down; the run is the amount of units we move right or left.
So here, we move 2 units up and 4 units to the right:
[tex]\frac{2}{4}[/tex]
We can reduce our fraction (divide the top and bottom by 2):
[tex]\frac{1}{2}[/tex]

how to solve: -4(2x - 5) = 3x -13
~one variable linear equation
==============================
-4(2x - 5) = 3x - 13
= -8x + 20 = 3x - 13
= -8x + 20 - 3x = -13
= -8x - 3x = -13 - 20
= -11x = -13 - 20
= -11x = -33
= x = -33 ÷ -11
= x = 3 ✔️

jessica saves quarters and dimes in a jar.She uses the expression 0.25q+0.1d to find the value of the coins the variable q is the number of quarters and the d is the number of dimes.Find the value of the coins when jessica has 18 quarters and 15 dimes.Show your work
Answer:
$6.00
Step-by-step explanation:
Total amount of money = 0.25q + 0.1d
where q is the number of quarters and d is the number of dimes
The problem states we have 18 quarters: d = 18
And that there are 15 dimes: d = 15
Plugging it in we get
= 0.25(18) + 0.1(15)
= 4.5 + 1.5
= 6.0

An electronics retailer sells a washing machine at cost price (how much the retailer paid for it) of $400 with a profit of 20%. What price does the customer pay?
Answer:
$480
Step-by-step explanation:
They sold the machine for $400 but made a profit of 20%.
This mean you would take 400 × .20
This gives you 80
That means the retailer got an extra 20% or $80
for the washing machine.
$400 + $80 = $480

Answer:
2
Step-by-step explanation:
Here we're "evaluating," not solving, the given expression.
Substitute -2 for x and 6 for y:
20 - (-2)^2 20 - 4
--------------- = -------------- = 16/8 = 2
(6) - (-2) 8
The value of this expression, when x = -2 and y = 6, is 2.
What does 4+24÷-6×2=
Answer:
-2, as the expression is written
Step-by-step explanation:
It depends on how one interprets the expression. The expression, as written, is:
4+24÷-6×2=
A fundamental rule in math is known as PEMDAS. This acronym describes the order of operations that are to be followed when solving mathematical expressions. PEMDAS stands for
P- Parentheses,
E- Exponents,
M- Multiplication,
D- Division,
A- Addition, and
S- Subtraction.
The use of parentheses is critical in math expressions, as we will see here.
The are no parentheses in "4+24÷-6×2=." So we will follow the steps are shown above:
Multiplication: 4+24÷-6×2 = 4+24÷-12
Division: 4+24÷-12 = 4+-2
Addition: 4+-2 = 2
The expression as written is equal to 2.
But if parentheses were included in the origianl proble, the answer might be different. For example:
(4+24)÷-6×2=
Parentheses: (4+24)÷-6×2= (28)÷-6×2=
Multiplication: (28)÷-6×2= (28)/-12
Division: (28)/-12 = -2.333 . . .
