The function n(d)=4•3^d-1 represents the number of people who receive a newspaper on day d of a delivery schedule. What does the value 3 represent in this situation?

1. Three people received a newspaper on the first day in the schedule

2. There are 3 people making deliveries

3. Deliveries were made for 3 days

4. The number of people receiving a newspaper on a given day is 3 times what it was the previous day

option 2 is correct.

step-by-step explanation:

we are given two inequality equation

x+y> 5 and -3x+2y< -2

first we draw the graph of both function using t-table method

equation: x+y> 5

for x=0, y=5

for x=-5, y=0

table:

x   :   0     5

y   :   5     0

test point (0,0) , 0> 5

false

equation: -3x+2y< -2

for x=0, y=-1

for x=2, y=4

table:

x   :   0     2

y   : -1       4

test point (0,0) , 0< -2

true

now we draw the graph. see the attachment for graph.

common region would be solution set.

option 2 is correct.
