Answer:
= {2, 4, 10}
Step-by-step explanation:
A set is a collection of objects called elements. These element are refered to as members of the set.
Set A contains all integers from 1 to 10 inclusive;
A = {1, 2, 3, 4, 5, 6, 7, 8, 9, 10}
A subset of a given set implies that every element of the subset are also elements of the given set. Set B is a subset of A;
B = {1, 3, 5, 6, 7, 8, 9}
Complement of a given set refers to elements not in the general set. Set C is the complement of B;
= {2, 4, 10}
Answer:
The friend's claim is not correct
Step-by-step explanation:
we know that
If two lines are perpendicular, then their slopes are opposite reciprocal (the product of their slopes is equal yo -1)
Example
A given line has a slope of ---> (is less than 1)
the slope of the line perpendicular to the given line is equal to
substitute
so
the perpendicular line don't have a positive slope
therefore
