Answer:
Step-by-step explanation:
a) Recall the quantifiers
.
Then, we can translate the proposition as follows

b) Recall that an expression of the form
its negation is of the form
which means that it is not true that for all elements the proposition P holds. Equivalently, we have that the negation of an expression of the form
is
which means that there is at least one x such that P doesn't hold. Using this, we get the following
By De Morgan's law, we have that
So, the final statement is

c)
This statement means: There is a movie that for every pair of students, at least one of the students hasn't seen the movie yet.
Answer:
less than, more than, more than, more than (in order)
Step-by-step explanation:
It depends on the number you're multiplying to 6 3/4.
For example, for the first one, the equation is 6 3/4 x 1/2.
Since 1/2 is less than 1, the answer will be less than 6 3/4.
Answer:
x = 4
Step-by-step explanation:
to find the zero let f(x) = 0 , that is
- 2x + 8 = 0 ( subtract 8 from both sides )
- 2x = - 8 ( divide both sides by - 2 )
x = 4
