A scientist is working with a colony of 5,000 bacteria. If the equation that models the population over time is y = 5000*1.5x. How many bacteria will there be in 5 hours?
A
35,000
B
37,500
C
32,800
D
37,968

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.
