A kite is flying 11 ft off the ground. It’s like pulled taut and casts a 6ft shadow. Find the length of the line. If necessary, round your answer to the nearest tenth.

12.5

Step-by-step explanation:

If you do 11 squared plus 6 squared it comes to 121 + 36= 157 but then you have to square root that to 12.5

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.
