Answer: 2
Step-by-step explanation:
I did this question before
Answer:
2x
aka 2
See below
I'm guessing you want to fill in the blanks of the sequence?
We can represent this as an equation:
31-3x=18
-3x=13
x=-13/3
Second term: 31 - (13/3) = 26 2/3
Third term: 26 2/3 - (13/3) = 22 1/3
p = -2
px + 2y + 8 = 0
px + 2y = -8
p(4) = -8
32x+540
(E) I, II and III
Given,
[email protected] = a + b - ab ∀ a, b ∈ Z ( set of all integers ),
For solving this question we need to remember the following properties of integers:
I. [email protected] = a + b - ab,
[email protected] = b + a - ba = a + b - ab
Thus, [email protected] = [email protected]
II. [email protected] = a + 0 - a × 0
= a + 0 - 0
= a
III. ([email protected])@c = ([email protected])+c - ([email protected])c
= (a + b - ab) + c - (a + b - ab)c
= a + b - ab + c - ac - bc + abc
= a + b + c - ab - bc - ac + abc,
Now, [email protected]([email protected]) = [email protected]( b + c - bc )
= a + (b + c - bc) - a(b+c - bc)
= a + b + c - bc - ab - ac + abc
= a + b + c - ab - bc - ac + abc.
Thus, ([email protected])@c = [email protected]([email protected])
