Answer: x = 27/2
Step-by-step explanation:
2/3x-2=7
2/3x=9
2/3x=27/3
2/3x(3/2)=27/3(3/2)
x=81/6
x=27/2
The inverse of the function f(x) = 
is : ![\sqrt[3]{x}](https://tex.z-dn.net/?f=%5Csqrt%5B3%5D%7Bx%7D)
<h3 /><h3>What is the inverse of a function?</h3>
The inverse of a function is that function that acts to undo a given function.
Analysis:
if f(x) = x^{3}, then let y =
![\sqrt[3]{y}](https://tex.z-dn.net/?f=%5Csqrt%5B3%5D%7By%7D)
= ![\sqrt[3]{x^{3} }](https://tex.z-dn.net/?f=%5Csqrt%5B3%5D%7Bx%5E%7B3%7D%20%7D)
x =
Replace y with x
h(x) =
in conclusion, the inverse of h(x) =

Answer: Brian should ask a price of £520 for the guitar.
Step-by-step explanation:
Given : Making cost of guitar= £325
Mark up percentage = 60%=0.60 [we divide percentage by 100 to convert into decimal]
Now , the price should be asked by Brian May for the guitar would be :
(Making cost of guitar) + 60% of (Making cost of guitar)
=(Making cost of guitar) + (0.60) x (Making cost of guitar)
= (Making cost of guitar) x (1+0.60) [By distributive property]
= (£325) x (1.60)
= £520
Hence, Brian should ask a price of £520 for the guitar.
