27. Replace b with 7, making 6 + 3(7). The 3 and parentheses of 7 hint multiplication, so you multiply to make 21, then add 6 relating back to PEMDAS to teach you the correct order to solve the problem.
The current rate is simply equal to $175 per month, let
us call this as rate A:
A = 175
The new rate is $94 plus $4.50 per devices, let us call
this as rate B:
B = 94 + 4.50 x
where x is the number of devices connected to the network
The inequality equation for us to find x which the new
plan is less than current plan is:
94 + 4.50 x < 175
Solving for x:
4.50 x < 81
x < 18
So the number of devices must be less than 18.
- From the graph, we can actually see that the new rate
intersects the current rate at number of devices equal to 18. So it should
really be below 18 devices.
Solving RootIndex 3 StartRoot 8 EndRoot Superscript x we get 
Step-by-step explanation:
We need to find equivalent to RootIndex 3 StartRoot 8 EndRoot Superscript x
Writing in mathematical form:
![(\sqrt[3]{8})^x](https://tex.z-dn.net/?f=%28%5Csqrt%5B3%5D%7B8%7D%29%5Ex)
Solving:
We know 8= 2x2x2= 2^3
and ![\sqrt[3]{x}=x^{\frac{1}{3}}](https://tex.z-dn.net/?f=%5Csqrt%5B3%5D%7Bx%7D%3Dx%5E%7B%5Cfrac%7B1%7D%7B3%7D%7D)
Applying these rules:



So, solving RootIndex 3 StartRoot 8 EndRoot Superscript x we get

F(x) = [x] - 2 + 8
[x] is the notation for 'greatest integer function'
f(-1.8) = [-1.8] - 2 + 8 = -2 -2 + 8 = 4
The answer is 4
If you multiply 268 with 6, you get 1608 as your answer.
