Answer:

Number of monthly calls = 475

Step-by-step explanation:

Given:

Plan 1 = $30 per month unlimited calls

Plan 2 = $11 + $0.04(per call)

Find:

Number of monthly calls, plan 1 better than plan 2

Computation:

Plan 1 (Cost) < Plan 2 (Cost)

30 < 11 + 0.04(x)

19 < 0.04(x)

475 < (x)

Number of monthly calls = 475

hodyreva [135]

Answer: The value of b is $0.15.

Step-by-step explanation:

Total bottles co0llected = 14+9 =23

Payment for each bottle = b

Total payment she will get = 23b

One -time service fee = $0.25

She has left = $3.20

According to the question,

23b - 0.25 = 3.20

⇒23b = 3.20+0.25

⇒23b = 3.45

⇒b = 0.15   [divide both sides by 23]

Cost of each bottle = $ 0.15

hence, the value of b is $0.15.

I don't understand the functions of a polynomial function?
Nitella [24]
So f(x)=x+10 lets say

so if you put something into the function lets say 5 then the function will do something to it and give you an answer so if you put in 5 for x you would get 5+10 or 15

a function of a function
lets say
f(x)=2x-9
g(x)=7x+2
    (g(x) is just another function represented by g instead of f)
so if you wanted  to put g(x) as x into f(x) and put x in g(x) to 3
then f(g(x))=2(7x+2)-9 or f(g(3))=2(7*3+2)-9=2(23)-9=37
hope this helps
