Answer:
The third one
Step-by-step explanation:
<span>Find the inverse function of f.
f(x)=(1+3x)/(5-2x)
Interchange x and y to get:
x=(1+3y)/(5-2y)
Solve for y as follows:
5x-2xy=1+3y
3y+2xy=5x-1
y(3+2x)=5x-1
y=(5x-1)/(2x+3)
this is the inverse function</span>
If you mean out of £48,
answer: £36:£12
C. 27 km.....if you want me to elaborate let me know
Expression: 2n - 1
When n = 7
2n - 1 = 2(7) = 1 = 14 - 1 = 13
