Grace, problem #22


Kallie and Chloe's answers #22

We set them equal to each other and then we turned it into a quadratic equation and then lastly we factored them and then set them to equal to zero

Aidan and Emily's Answer to problem #22

We made both equations equal to 0, and then we plugged them into a calculator. Next we scoured all the answers until we found 20 and 130. The journey had been completed, successfully!

Camsandra's correct #22

22) Tyler Roy

I just kept increasing the window settings until I saw where they intersected, hit 2nd calc and placed my boundaries. After I plugged x=20 into both equations and they came out the same.

X: 0,50
Y: 0,5000






Alex's skillful guess and check method

I set the equations equal to each other, checked the table in my calculator and plugged them in. After guessing and checking of course.

Problem 22-Ashley

I set the two equations equal to each other and then I made the two equations into one and set that equal to zero and solved using the AC method

Problem #22 Mike C Ben E


 found the x value where both of the equations were equal. This x value was 20.

Jennifer's answer

I took both equations and set them equal to each other; then I factored the equation. next I plugged in 20 and 130 into both the original equations to check my work.
