A biologist studied the populations of common guppies and Endler’s guppies over a 6-year period. The biologist modeled the populations, in tens of thousands, with the following polynomials where x is time, in years.
common guppies: 3.1x2 + 6x + 0.3
Endler’s guppies: 4.2x2 – 5.2x + 1
What polynomial models the total number of common and Endler’s guppies?

  1. just add them up:

    3.1x^2+6x+0.3
    4.2x2-5.2x+1
    ----------------------
    7.3x^2+0.8x+1.3

  11. I am honestly surprised that you guys still don't know that everyone's math tests are different they do this to prevent cheating. Everyone has eight to ten personalized questions so google each individual question. Its worth your grade !!!!!

    Ps: This only applies to math TESTS so cheat away on everything else

  14. Let me tell you all this 📢. Don't just write answers! When you write the answers make sure you write from what state your from cuz every state has different answering techniques. So If you have answers write the answers and write wherever you want as long as we can see it write the state name!! 👏
