Answer:
The number of non empty proper subsets of a set with 3 elements is =23−2=8−2=6.
Your selection is correct.
A good way to solve these problems is to first figure out the system if the functions were regular equalities. Then, to determine which direction the inequality sign goes, ask whether the graph is shaded above or below y. For above, that means y is greater than... below, less than. A solid line means greater/less than or equal to.
Step-by-step explanation:
it has 4 sides, all of whick are equal. Answer is 4*4, 16.
The unit rate for $240 per 4 days is $60 per 1 day.
To get a unit rate you must simplify the rate down to $X per 1 day.
To get 4 days down to 1 day you must divide 4 by 4.
Doing the same to the other side you divide 240 by 4.
So now you have $60 per 1 day.
