The expression below represents the total cost in dollars, including shipping, for a certain number of music CDs, m. 8m + 5. Based on the expression above, what is the total cost for 4 music CDs? A. $13 B. $17 C. $32 D. $37

what are the options? ?

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.

answer: 8d

step-by-step explanation:

45+5= 50+5=55+5=60

step-by-step explanation:

graph using a few selected

x         y

-1       15

0         6

1         2.4

2       0.96
