Although not so common now, consider a phone plan that does not have unlimited texting. your base plan costs you $30 a month and each text sent or received is only 12 cents. write an equation to describe the total monthly cost of your bill with x text messages and y cost.
in one month 217,000 messages were sent between two brothers in philadelphia. what was their approximate bill? (this is a true story! )

The bill will be $26070.

Step-by-step explanation:

Your base plan costs you $30 a month

And each text sent or received is only 12 cents or $0.12.

Let the messages sent be = x

So, cost for messages become =

Let total bill cost be = y

Now, total bill will comprise of monthly plan charges plus message charges.

So, equation forms:

Now, given is that In one month 217,000 messages were sent between two brothers in Philadelphia.

So, their approximate bill will be :

=>

=> y = 26070

Therefore, bill will be $26070.

show us the graphs dude

step-by-step explanation:

problem:

f(x) = - 2/3x + 5; f(5/2)

substitute 5/2 in for x:

f(5/2) = -2/3(5/2) + 5

simplify the right side:

f(5/2) = -5/3 + 5

f(5/2) = 10/3

f(5/2) = 10/3

i hope this !
