Answer: The correct order of the options is 4, 3, 2, 1 and 5.
Explanation:
The steps for analyzing mathematical models are,
To analyzing a mathematical model first we have to defined the problem and identify parameters.
The second step is, defined the data needed. it means determine that which type of data is required according to the problem and parameters and neglect the relevant data.
The third step is collect or gather needed data. To solve the defined problem we need the related data.
The fourth step is arrange or analyse the data according to the requirements.
THe fifth step is after analysing the data draw a reasonable conclusion.
Therefore, the correct order of the options is 4, 3, 2, 1 and 5.
Start by taking the information we know, and write equations to represent the realationships:
1) "1/8 lbs less flour to make bread than to make cookies"

2) "1/4 lb more flour to make cookies than to make brownies:

3) "she used 1/2 lb of flour ro make bread"

From here you can solve for

using back substitution.
Its b because to simplify radical you multiply by in this instance sqrt of 5 on the denominator and numerator
The first graph is what i would think
