Karri puts $1600 into an account that does not earn any interest. Every month
after that, she deposits the same amount of money. This sequence
represents her account balance for the first few months.
$1600, $1900, $2200,...
What is the explicit formula for the amount of money in her account at the
beginning of month n?

1600 + 300n = balance

Step-by-step explanation:

n = number of months

1600 + 300(12) =

1600 + 3600 = 5200

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.

the answer is b.
