Answer:
it's 0 I think im not that smart you know xD
have a good day :)
Step-by-step explanation:
The answer is
-2 x + 2 y^2 + 4 y - 9.
Hope this helps! :D
B u A = 48
B = 45
The part of set B not included in A is B - A∩B = 45 - 7 = 38
Since B u A = 48, A must have 48-38 = 10 elements (3 exclusive of B, 7 shared with B).
------
Alternatively, the inclusion-exclusion principle may be used: A + B - (A ∩ B) = A u B
A + 45 - 7 = 48
A = 48 - 45 + 7
A = 10
NOTE that I'm using A and B to indicate the number of elements in each set, respectively.
More formally, one would write |A| and |B| to indicate the cardinality (number of elements) of the set.
Answer:
(1/2,1) is on the graph of 
B is correct.
Step-by-step explanation:
Given:
We are given a log function whose base 1/2.
Log property:
If base and mantissa is same then their value is 1
We need to choose correct point from the options.
Option 1: (1,1/2)
False
Option 2: (1/2,1)
True
Option 3:
Log is not defined for x=0.
Hence, (1/2,1) is on the graph of
