Answer:
f^−1(x)=2^x/4
Step-by-step explanation:
The inverse of the function will be;
⇒ [tex]f ^{-1} (x) = \frac{2^{x}}{4}[/tex]
What is Function?A relation between a set of inputs having one output each is called a function.
Given that;
The function is,
⇒ y = log₂ (4x)
Now,
Since, The function is,
⇒ y = log₂ (4x)
Find the inverse of the function as;
⇒ y = log₂ (4x)
⇒ [tex]2^{y} = 4x[/tex]
⇒ [tex]\frac{2^{y}}{4} = x[/tex]
⇒ [tex]f ^{-1} (x) = \frac{2^{x}}{4}[/tex]
Thus, The inverse of the function y = log₂ (4x) is,
⇒ [tex]f ^{-1} (x) = \frac{2^{x}}{4}[/tex]

x is inversely proportional to the square root of y
When x = 12, y = 9
Find the value of x when y= 81
Answer: 4
Step-by-step explanation:
The formula for inverse proportion is x = k / y. Since x is inversely proportional to the square root of y. This will be:
x = k / ✓y
When x = 12, y = 9
We have to calculate the constant of proportionality, k which will be:
12 = k / ✓9
12 = k / 3
k = 12 × 3
k = 36
To find the value of x when y = 81 will be:
x = k / ✓y
x = 36 / ✓81
x = 36 / 9
x = 4
Therefore, x = 4 when y = 81.

Step-by-step explanation:
First, list the multiples of each numbers and stop when you reach the least common multiple (the smallest number the numbers can multiply up to):
5: 5, 10, 15, 20, 25, 30, 35, 40, 45, 50, 55, 60, 65, 70, 75 . . .

Hello Solving Equations Puzzle
Answer:
Pink Trapezium = 30 as 30 x 1 = 30
Purple Diamond = 2 as 2 x 2 = 4
Green Moon = 7.5 as it shares the line with 4 it goes 4 x 7.5 = 30
The weight of the line is dividing line just the same as multiple when we find the numbers from dividing. But work out 2 x 2 first. then use that number to divide into 30 to find 7.5.
When we show the values see below. We have 30 also for the second line so both lines are equivalent
Step-by-step explanation:
I would multiply as addition is just too easy.
Pink Trapezium is 1 x 30 = 30 = 30/1 = 30 value
Purple diamond = 2 x 2 = 4 = 4/2 = 2 value
Green Moon is 30/4 = 7.5 value

find the median.
Answer:
Median is 18
Step-by-step explanation:
Firstly you have to fine y by using your mean
Therefore, 22+18+(2y+1)+10+20 divide it by the number of the mean that is the sum of the number divide by the total number of the mean which is 5 =15
22+18+2y+1+10+20 over 5 =15
