Verizon Wireless offers an internet plan for $20 a month plus a $20 setup fee. Consolidated Communications offers an internet plan for $25 a month plus $10 setup fee. After how many months will be equal? Which plan is more economical in the long term?

Verizon Wireless offers better plan

Step-by-step explanation:

Now it is easiest to calculate an yearly cost for both companies.

First calculate cost for Verizon

If y is annual payment and x is monthly payment

Relation is

y = 20 + 12x

y = 20 + (12)(20)

y = 260

So for Verizon wireless, annual amount is $260

Now calculate cost for Consolidated Communication

If y is annual payment and x is monthly payment

Relation is

y = 10 + 25x

y = 10 + (12)(25)

y = 310

So for Consolidated Communication, annual amount is $310.

Here by comparison we can see that the offer of Verizon Wireless is better in long term.

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.
