21 feet rope costs $28.35

Step-by-step explanation:

First, we have to see how much 1 foot rope costs. To do this, we have to do 20.25 / 15

20.25 / 15 = 1.35

Now that we know how much 1 foot costs, now we have to see how much 21 feet costs by doing

1.35 x 21

1.35 x 21 = 28.35

So, 21 feet rope costs $28.35

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.
