Folding a paper will make it thickness become double from it before.
Unfolded paper has 1 thickness
1 times folded paper has 2 thickness
2 times folded paper has 4 thickness
3 times folded paper has 8 thickness
From here it is clear that the pattern is
. SInce the paper is 0.1mm, then the function would be:
f(n)=
x 0.1mm
Answer:
x = 11/7 y = -1/7
Step-by-step explanation:
2x + y = 3
2x + y - 2y = 3 - 2y
y = 3 - 2x
x - 3(3 - 2x) = 2
x - 9 + 6x = 2
x - 9 + 6x + 9 = 2 + 9
x + 6x = 11
7x = 11
7x / 7 = 11/7
x = 11/7
2(11/7) + y = 3
22/7 + y = 3
22/7 + y - 22/7 = 3 - 22/7
y = -1/7
