-1+(-4)= -1-___ can you please help

-1+(-4)=-1-4

Step-by-step explanation:

-1+(-4)=-1-4

numbers after (+) sign, no need to change signs

the number after (+) is -4, so we keep the (-) sign, which will be:

                                       -1+(-4)=-1-4

Hope this helps!! :)

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.
