Jabari and mekhi decided to start a construction business. they have $20,000 and at the end of seven years, they realized that repaid the bank of gresham and smith $44,000.what was the interest rate for loan?

47 - 90 = 43

43 - 180 = x

x = 137

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.
