The weight of a bunch of graphs is estimated to be 3 lbs. The actual weight is 2.7 lbs. What is the percent error in the estimate? Enter your answer, rounded to the nearest tenth, in the box.​

11.1%

Step-by-step explanation:

(3 - 2.7)/2.7 = 11.1%

(measured - true) x 100 = percent error

          true

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.
