Rachel has 26 dimes. She is getting rolls of dimes from the bank. She has enough money to get
up to 8 rolls of dime and each roll contains 50
dimes. The bank will not give partial rolls. The
function that models the number of dimes Rachel
will have after leaving the bank is f(r)=50r+26,
where r is the number of rolls of dimes she gets.
What is the practical domain of the function?

step-by-step explanation:

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.
