Answer:
$ 584.89
Step-by-step explanation:
so each student is responsible for selling 12 necklaces...and there are 130 students....so thats (130 * 12) = 1560 necklaces
each necklace is 1.50....so thats (1560 * 1.50) = 2340
profit = revenue earned - expenses
profit = 2340 - 0.45 = 2339.55
1/4 of the profit goes to Puerto Rico
1/4 * 2339.55 = 2339.55/4 = 584.887 rounds to $ 584.89 <==

Answer:
-7 is in our domain.
0 is in our domain
7 is not in our domain.
Step-by-step explanation:
So we have the rational function:

The domain restrictions of rational functions are the zeros of the denominator. In other words, the domain of rational functions are always all real numbers except for the zeros of the denominator.
So, solve for the denominator by setting it to 0:

Add 7 to both sides:

So, our domain is all real numbers except for 7.
(When x=7, we have 7/0, which is undefined.)
Therefore:
-7 is in our domain.
0 is in our domain
7 is not in our domain.
well, my idea is plot a line on XOY plane. let the number line as x-axis, make y-axis, we just need a line that cross (1/6,0) for example y = x/6 - 1/6, next we need two simple pair number (x,y) on the line as base to draw the line we can choose (1,0) and (7,1). x-intersect that line is desired 1/6 position on the number line
