Answer:
–x² + 12x + 5
Step-by-step explanation:
x² + 3x
–2x² + 9x + 5
The sum of the above expression can be obtained as follow:
.... x² + 3x
+ –2x² + 9x + 5
¯¯¯¯¯¯¯¯¯¯¯¯¯¯¯¯¯¯¯¯
–x² + 12x + 5
¯¯¯¯¯¯¯¯¯¯¯¯¯¯¯¯¯¯¯¯
Thus, the sum of x² + 3x and –2x² + 9x + 5 is –x² + 12x + 5

1 equation goes with the graph one, 2nd equation goes with 4th graph , 3rd equation goes with 3rd graph, and 4th equation goes with graph graph 2.
If the equation is...
y=c, where c is a constant, the line is horizontal across that c value, on y axis. x=c the line would be vertical across that c, on x axis.
