Answer:
The second one (4+3x = 9)
Step-by-step explanation:
From the working we can already tell that the second one is the odd one out without even doing the 4th one
First off, you have to make 65 % into an actual number, which is 0.65 (every time you want to convert percentages into numbers, you have to divide that by 100)

the equation is y= -|x+3|, where '-' means location of graph in the 3-d quarter, '+3' - the graph is moved to the left on 3 points.





The second equation gives

, but

for any real

, so we can ignore this equation.
This leaves us with

where

is any integer.
