hope it helps
sorry, I didn't know how to explain it
1487.93 should be the correct answer I believe.
Answer:
Q=(2,-1)
Step-by-step explanation:
We are given point as N=(-1,2)
Point Q is symmetric to point N with respect to line y=x
we know that any point symmetric with respect to line y=x means inverse of that point
For example: If we have to find symmetric about y=x line of point (a,b)
a changes to b
and b changes to a
so, symmetric of (a,b) with respect to y=x line would be (b,a)
We have point N(-1,2)
-1------>2
2----->-1
so, we get point as
Q=(2,-1)
Answer:
The statement can be expressed as
There are two different students in your class who have visited the same websites.
Step-by-step explanation:
Given that
- W(x, y) mean that student x has visited website y.
- The domain of x consists of all students in your school
- The domain of y consists of all website.
It would help to know the meaning of the symbols used, this will help understand the statement better.
- ∧ means conjuction
- ∃ means 'there exists'
- ∀ means 'for all'
- ≠ means 'different from'
- ↔ means 'if and only if'
The statement
∃x∃y∀z((x ≠ y) ∧ (W(x, z) ↔ W(y, z)))
can be expressed as:
There are two different students in your class who have visited the same websites.
