At Noise Pollution Cellular, plan A is $30.00 per month and $5.00 for every gigabyte of data. Plan B is $50.00 per month and $2.00 for every gigabyte of data used. Irfan wants to find out which plan is the best choice for him. On average, he uses five to eight GB of data per month.How much data would Irfan need to use for both plans to cost the same?

Answer:
Part 1) The best choice is Plan A
Part 2) The data is
Step-by-step explanation:
Part 1)
Let
y ----> the cost per month
x ----> the number of GB of data per month
we know that
Plan A
Plan B
Find out which plan is the best choice if he uses five to eight GB of data per month
Plan A
For x=5 GB -----> y=5(5)+30=$55
For x=8 GB -----> y=5(8)+30=$70
so
with Plan A the cost is between $55 and $70 -----> average $62.5
Plan B
For x=5 GB -----> y=2(5)+50=$60
For x=8 GB -----> y=2(8)+50=$66
so
with Plan B the cost is between $60 and $66 ----> average $63
therefore
The best choice is Plan A
Part 2) How much data would Irfan need to use for both plans to cost the same?
we have
y=5x+30 ----> equation A
y=2x+50 ----> equation B
Solve the system of equations by elimination
Subtract equation B from equation A
0=5x-2x+30-50
0=3x-20
3x=20
Convert to mixed number
----> for this data the cost is the same in both plans

Both 180 seconds or 3 minutes are equal.
What is division?
The division in mathematics is one kind of operation. In this process, we split the expressions or numbers into the same number of parts.
Given:
We have two times,
180 seconds and 3 minutes.
180 seconds in minutes,
= 180/60
= 3 minutes.
Therefore, both are the same.

how you find the answer is you divide 60 into 180 and you get 3 which means 3 minutes so their both the same

the standard line equation is y = mx + b, where y is the y point, x is the x point, m is the slope, and b is the y-intercept.
to get the y intercept, we need to transform into the line equation, and caculate out b.

The value of the functionf(x) = 4x +5 at x = 5 is f(5) = 25
What is function?
"It is a relation from a set of inputs to a set of possible outputs where each input is related to exactly one output."
For given example,
Given function: f(x) = 4x +5
We need to find the value of f(x)
This means, we need to find the function f(x) when x = 5
Substitute x = 5 in the given function.
⇒ f(x) = 4x +5
⇒ f(5) = 4(5) +5
⇒ f(5) = 20 + 5
⇒ f(5) = 25
Therefore, f(5) = 25

F(5) is 0 at this point
Subtract 5 from both sides
-5=4x
Divide both sides by 4
-5/4=x
So f(5)=-5/4
