When Brad's group completed the Bungee Barbie with a Ken doll, they found out if they attached 5 rubber bands to his feet, he fell 10 inches. if they attached 8 rubber bands, he fell 27 inches. Write an equation using the data given.

anonymous · Answer

hmmm... what kind of equation?

31356 · Answer

y= ......

anonymous · Answer

oh ok :D

anonymous · Answer

y = 5.67x - 18.33 OR y = 16/3 x - 55/3

31356 · Answer

Okay thanks!
Need your help 2 more problems...

anonymous · Answer

ok

31356 · Answer

If Ken wants to jump off a cliff that is 260 inches in height, what is the maximum number of rubber bands he can use without dying?

anonymous · Answer

so using the equation: y = 5.67x - 18.33 from above,
you plug in the value 260 for y:
260 = 5.67x - 18.33
x = 49.008

31356 · Answer

Okay thanks!
One more problem left!

anonymous · Answer

Ok! :D

31356 · Answer

If Ken gained weight and now falls 50 feet with 5 rubber bands and 60 feet with 8 rubber bands, how would that change the graph.

31356 · Answer

Lol imagine Ken gaining weight....

anonymous · Answer

He now weighs more, so that would mean that the rubber bands would have to stretch more due to his weight, so it would shift. It would now be y = 0.3x - 10
