Hello,
f^(-1)(f(x))=f^(-1)(1/2 * x)=2*(1/2 * x)=(2*1/2)*x=1*x=x
f(f^(-1)(x))=f(2x)=1/2* (2x)=(1/2*2)*x=1*x=x
The percentage of 4c that's the expression 0.04c will be is 1%.
<h3>How to calculate the percentage?</h3>
From the complete information, we are told to calculate the percentage of 0.04c from 4c.

The solution to the given simultaneous equation is; (-9, -10)
<h3>What is the solution to the simultaneous equations?</h3>
We want to solve the simultaneous equations;
y = ²/₃x - 4 ----(1)
y = ⁴/₃x + 2 ----(2)
Subtract eq 1 from eq 2 to get;
⁴/₃x - ²/₃x + 2 + 4 = 0
²/₃x = -6
x = (-6 * 3)/2
x = -9
Thus;
y = ⁴/₃(-9) + 2
y = -10
Thus, the solution to the given simultaneous equation is; (-9, -10)
