Answer:
x = -2, y = -3
Step-by-step explanation:
y - 3x = 3
x - 2y = 4
-3x + y = 3
x - 2y = 4
-6x + 2y = 6
x - 2y = 4
Add the equations.
-5x = 10
x = -2
Substitute -2 for x in the first original equation and solve for y.
y - 3x = 3
y - 3(-2) = 3
y + 6 = 3
y = -3
Answer: x = -2, y = -3

B) ω= 1+4+6+4+1= 16 = number of sample space, which is = to n.
C) the random variable should 3.14 approximately or 22/7
Answer:
3p + 3 = 18
3p = 18 -3
3p = 15
p = 15/3
p= 5
Step-by-step explanation:
If a graph is proportional then the line will go through the origin at point (0, 0). If the equation is proportional then it will be in the form of y=kx with no other operations after. The constant of proportionality is another way to say the slope and in your specific equation the slope would be 1/5.
