Plz answer to hard plz help 1+1

umm so I didn't understand ur question but if it is 1+1

then the answer is 2

This question was really hard it took some time to finish. 2

Step-by-step explanation:

1+3=4-1=3+6=9-6=3+17=20-10=10-8= 2

check above link.

graphically?   well, you graph them both, the solutions is where they both intersect each other, since there are two solutions, meaning they will meet twice, or namely the linear will run into the quadratic curve twice, and where they meet, those x,y coordinates are the solutions to the system.

i believe the answer is c.
