Answer:
see explanation
Step-by-step explanation:
Given the 2 equations
- 6x - 4y = 2 → (1)
- 4x - 7y = 2 → (2)
Multiplying (1) by 4 and (2) by - 6 will eliminate the x- term
- 24x - 16y = 8 → (3)
24x + 42y = - 12 → (4)
Add (3) and (4) term by term
26y = - 4 ( divide both sides by 26 )
y =
= - 
Answer:
A = - 2 and B = - 8
Step-by-step explanation:
A = - 2 and B = - 8 will create infinitely many solutions for this system of equations
When you add both equations together and both sides are equal then the systems have infinitely many solutions
-2x - y = 8
2x + y = -8
--------------------Add
0 = 0
Both sides are equal 0
Infinitely many solutions
I believe that 7/45 is a repeating decimal
You made a mistake with the probability
, which should be
in the last expression, so to be clear I will state the expression again.
So we want to solve the following:
Conditioned on this event, show that the probability that her paper is in drawer
, is given by:
(1)
and
(2) 
so we can say:
is the event that you search drawer
and find nothing,
is the event that you search drawer
and find the paper,
is the event that the paper is in drawer 
this gives us:


Solution to Part (1):
if
, then
,
this means that

as needed so part one is solved.
Solution to Part(2):
so we have now that if
=
, we get that:

remember that:

this implies that:

so we just need to combine the above relations to get:

as needed so part two is solved.
