The inverse function is the original function reflected over y=x option (B) is correct.
What is a function?It is defined as a special type of relationship, and they have a predefined domain and range according to the function every value in the domain is related to exactly one value in the range.
We have a statement:
The graph of an inverse function compare to the original function:
As we know, every function with domain real numbers can be plotted on graph paper or a coordinate plane.
Let f(x) = ax + b
or
y =ax + b
a and b are the real numbers
To find the inverse of a function interchange the value of x and y
f⁻¹ = x = ay + b
If we plot the above two functions we will see that f(x) is the mirror image of f⁻¹ over the line y = x.
Thus, the inverse function is the original function reflected over y=x option (B) is correct.

Find the inverse of each function. g(x)=∛(x-2)
Please show the steps. I can show you what I have so far if you want, too.
Just please don't put some Ludacris thing, like "ldsnvlsjdsv" Okay? thankyou :)
Answer:
x=2
Step-by-step explanation:
g(x)=∛(x-2) -Substitute g(x)=0
0=∛(x-2) -Swap the sides of the equation
∛(x-2)=0
∛(x-2)=0 -Set the radicand equal to 0
x-2=0
x-2=0 -Move the constant to the right hand side and change its sign
x=2

Please help! I do not know how to find the unknown variables using the Pythagorean theorem. Any help will be greatly appreciated:))
Answer:
x=10.247
y=52.02
z=37.98
Step-by-step explanation:
For x you use Pythagorean theorem which, in this situation would be 13^2=8^2+x^2 rearranging this we can figure out x by taking the square root of 13^2-8^2.
For y you can use any trig function but I chose to use cos since that uses info we're given, to find y you just do the inverse cos or cos^-1 of 8/13 to find the angle
For z you can use any trig function but I chose to use sin since that uses info we're given, to find z you just do the inverse sin or sin^-1 of 8/13 to find the angle

What is the least common denominator of
1/3 and 5/9
Answer:
LCD = 9Equivalent Fractions with the LCD
1/3 = 3/9
5/9 = 5/9
Solution:
Rewriting input as fractions if necessary:
1/3, 5/9
For the denominators (3, 9) the least common multiple (LCM) is 9.
LCM(3, 9)
Therefore, the least common denominator (LCD) is 9.
Calculations to rewrite the original inputs as equivalent fractions with the LCD:
1/3 = 1/3 × 3/3 = 3/9
5/9 = 5/9 × 1/1 = 5/9

This cylinder has a volume of 12cubic inches and a diameter of 4 inches.
Find the cylinder's radius and height.
h
Answer:
0.9554
Step-by-step explanation:
d = 4
r = d/2
r = 4/2
r = 2
V = 12
V = pi r^2 h
V = 3.14 * 2^2 * h
12 = 3.14 * 4 * h
12 = 12.56 * h
h = 12 / 12.56
h = 0.9554

b is directly proportional to a.
b is 10 when a is 8.
Work out b when a is 9.
Answer:
B=11
Step-by-step explanation:
b=10 a=8
b=? a=9
Either you can cross multiple 10x9=90/8 (11.25, round down to 11), or you can look that 9 is 8+1, so of we do the same process to b then we would find our awnser. 10+1=11.
When a is 9 then, the value of b will be;
⇒ b = 45/4
What is Proportional?
Any relationship that is always in the same ratio and quantity which vary directly with each other is called the proportional.
Given that;
'b' is directly proportional to a.
And, b is 10 when a is 8.
Now,
Since, 'b' is directly proportional to a.
Hence, We get;
⇒ b = ka
Where, k is constant of proportionality.
Here, b is 10 when a is 8.
So, Put b = 10 and a = 8;
⇒ b = ak
⇒ 10 = k × 8
⇒ k = 10 / 8
⇒ k = 5/4
So, When a is 9 and k is 5/4, then;
⇒ b = ak
⇒ b = 9 × 5/4
⇒ b = 45/4
Thus, The value of b = 45/4

Given the Trapezoid ABCD
Find the length of AD
Answer:
AD = 230
Step-by-step explanation:
here, we want to find the measure it AD
To do this, we need the value of x firstly
To get this, we are going to use the trapezoid midpoint theorem
The theorem is that the sum of the two parallel sides of a trapezoid when divided by 2 will give the middle point length of the trapezoid
Applying this:
1/2{30x-10+ 30x + 28} = 31x + 1
2(31x + 1) = 60x+ 18
divide both sides by 2
31x + 1 = 30x + 9
31x -30x = 9-1
x = 8
But;
AD = 30x-10
AD = 30(8)-10
AD = 240-10
AD = 230

Step-by-step explanation:
Looking at the problem, a cell phone company charges $20 for a new account, and $35/month for phone service. With that information we can quickly form this equation:
y = 20 + 35x
The y is the total cost, 20 is the initial charge, and 35x is the per-month charge.

Answer:
x=8 y=1
Step-by-step explanation:
you have first and second equation, YOU MUST FIND THE THIRD EQUATION
SOLUTION
FIND equation 3 from 2
x+2y=10
x=10-2y...........3
Substitute equation 3 from first (not from the equation where you got equation 3)
2 (10-2y)-7y=9
20-4y-7y=9
-11y=9-20
-11y= -11
-11y/-11= -11/-11
y=1
Find the value of x from the third equation
