Answer:
(third opti0n)
Step-by-step explanation:



For number 1 ↓
A) Cards increase the score by 8 points → <span>5 + 3; 4 + 4</span>
B)Cards decreased the score by 9 points→ <span>-29 + 20; -2 +-7</span>
C) Removing cards that increase the score by 10 points → <span>-4 + -6 & -5 + -5 </span>
D. Positive cards that decrease the score by 18 points. → Well since their aren't "positive card" that'll decrease the score. It might be negative cards which will decrease the scores
For number 2 ↓
Number of Cards → 5 | -3 | -4 | 3|
New cards: 5 | -12 | 4 | 3|
5 + -12 + -4 + 3 = -8
For number 3.↓
12: |-6 | -6|
8: |4 | 4 |
So, the numbers of "cards" hand would: -6 | -6 | 2 | 2| 2| 2 | ; 4| 4

means to say that for any given
, we can find
such that anytime
(i.e. the whenever
is "close enough" to 5), we can guarantee that
(i.e. the value of
is "close enough" to the limit value).
What we want to end up with is

Dividing both sides by 3 gives

which suggests
is a sufficient threshold.
The proof itself is essentially the reverse of this analysis: Let
be given. Then if

and so the limit is 7. QED
Definitely irrational because the decimal never repeat
