If the line containing the coordinate "k", is parallel to the line at 5,5 and 1,-4, then their slopes must be the same, since parallel lines, have the same slope, let's check both slopes then.
Just do this :
-1 + 30 - 5y
29 - 5y
or -5y + 29
the answer is C
1/5 + 1/3·x > 1/2·x - 1/4
1/3·x - 1/2·x > - 1/4 - 1/5
2/6·x - 3/6·x > - 5/20 - 4/20
- 1/6·x > - 9/20
1/6·x < 9/20
x < 54/20
x < 27/10
x < 2.7
Answer:
12x = cost
Step-by-step explanation:
12$ per ticket, with x tickets
you multiply the cost of a ticket with the number of tickets he will buy
The following subsets you can be able to create are:
{1}
{2}
{3}
{1,2}
{1,3}
{2,3}
{1,2,3}
Therefore, there are 7 subsets in all. However, we don't have to list all these possible outcomes because we could waste our time doing this but there is a formula, that is 2^n - 1 where n is a number of elements.
In the given, since there are 3 elements inside the set then we use 2^3 - 1 = 8 - 1 = 7.
See...it's easy.
