Since it's just asking for the other side of the diameter, it's equivalent to the radius given already.
1)
I:y=3x-4
II:9x-3y=14
substitute y into II:
9x-3*(3x-4)=14
9x-9x+12=14
12=14
this is obviously not equal so there is no solution, the lines are parallel
2)
I:y=4x+6
II:5x-y=6
substitute y into II:
5x-(4x+6)=6
5x-4x-6=6
x=12
substiute x into II:
5*12-y=6
-y=6-60
-y=-54
y=54
the solution is (12,54)

Step-by-step explanation:
A deck of cards have 52 cards. There are 4 suits of 13 card each, those suits are Hearts, Clubs, Diamond and Spades.
The probability that the first card is a heart is:
![P(Hearts) = \frac{13}{52}](https://tex.z-dn.net/?f=P%28Hearts%29%20%3D%20%5Cfrac%7B13%7D%7B52%7D)
Now, the probabily that the second card is a diamond is:
![P(Diamond | First card is Heart) = \frac{13}{51}](https://tex.z-dn.net/?f=%20P%28Diamond%20%7C%20First%20card%20is%20Heart%29%20%3D%20%5Cfrac%7B13%7D%7B51%7D)
The Probability that the first card is a heart and the second one a diamond is given by:
×![P(Diamond | First card is Heart)](https://tex.z-dn.net/?f=P%28Diamond%20%7C%20First%20card%20is%20Heart%29)
![= \frac{13}{52}\frac{13}{51}](https://tex.z-dn.net/?f=%3D%20%5Cfrac%7B13%7D%7B52%7D%5Cfrac%7B13%7D%7B51%7D)
