A cardinal number of a set is the number of elemenents it contains. Therefore the cardinal number of A is equal to 5.
Answer:
1) -3x + 5 = -10
-3x = -15
x= -15/-3
X = 5
3) 4-6x = -8
-6x = -8-4
-6x = -12
X = 2
2) 2(x-5)= -5
2x - 10 = -5
2x = 5
x = 2.5
4) -0.5(2x+6) = -6
-x -3 = -6
-x = -6+3
-X = -3 ( both negative will get cancel)
X = 3
Using log rules:
when you divide and then sperate you subtract.
So
Log3(5/x^2) would be A
Log3(5)-Log3(x^2)
