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

Prove the following limit. lim x → 5 3x − 8 = 7 SOLUTION 1. Preliminary analysis of the problem (guessing a value for δ). Let ε
Temka [501]

\displaystyle\lim_{x\to5}3x-8=7

means to say that for any given \varepsilon>0, we can find \delta such that anytime |x-5| (i.e. the whenever x is "close enough" to 5), we can guarantee that |(3x-8)-7| (i.e. the value of 3x-8 is "close enough" to the limit value).

What we want to end up with is

|(3x-8)-7|=|3x-15|=3|x-5|

Dividing both sides by 3 gives

|x-5|

which suggests \delta=\dfrac\varepsilon3 is a sufficient threshold.

The proof itself is essentially the reverse of this analysis: Let \varepsilon>0 be given. Then if

|x-5|

and so the limit is 7. QED
