what do you think the pattern is?
Phebe
  • Phebe
for which question A. B. or C.
anonymous
  • anonymous
for the table. you need the pattern to do them all.
Phebe
  • Phebe
well i think the pattern is going by 4 right?
anonymous
  • anonymous
no. It started at 1, then added 2, then added 4, then added 8. What would be the next number added?
Phebe
  • Phebe
i think 12
anonymous
  • anonymous
Each line is adding 2 times the last number added, so when x = 5 y = 1 + 2 + 4 + 8 + 16
anonymous
  • anonymous
because 2*8 = 16
Phebe
  • Phebe
OMG!! THATS TRUEE I WAS ADDING THE WHOLE TIME THAS Y I GOT IT WRONG
Phebe
  • Phebe
THANK YOU!!
anonymous
  • anonymous
you're welcome. you got if from here?
Phebe
  • Phebe
Yep i do Well Can you help me with the B part?
anonymous
  • anonymous
ok. the first thing you want to do is turn those sums into numbers like this |dw:1434049238139:dw|
Phebe
  • Phebe
ok
anonymous
  • anonymous
from there if you know your exponents you should see the pattern. |dw:1434049509172:dw| Your y-values are 1 less than 2^x
Phebe
  • Phebe
OH yea truee
Phebe
  • Phebe
thanks!
anonymous
  • anonymous
you're welcome

  • Phebe
Do you mind helping me with C?
Phebe

@peachpi
anonymous
  • anonymous
ok. how would you write the equation from the pattern we found in b?
Phebe
  • Phebe
im not shure
anonymous
  • anonymous
We have in the third column and expression for x. The second column is y. What's the relationship between numbers in the 2nd and 3rd columns?
Phebe
  • Phebe
i actually dont see a relatipnship between them at all
anonymous
  • anonymous
subtract the numbers in the 3rd from those in the 2nd and tell me what you get?
Phebe
  • Phebe
OK
Phebe
  • Phebe
2-1=1 3-4=1 7-8=1 15-16=1
anonymous
  • anonymous
those should be -1.
Phebe
  • Phebe
ok
anonymous
  • anonymous
so if you subtract 1 from 2^x you get y
Phebe
  • Phebe
Yes
Phebe
  • Phebe
so was that the answer?
Phebe
  • Phebe
????????????????????????
anonymous
  • anonymous
yes
Phebe
