a.
To write an expression to represent the given model and simplify.
a.
Answer to Problem 45IP
Explanation of Solution
Given:
The algebraic model
Calculation:
In order to write an expression to represent the given model, observe that the model contains seven 1’s plus 4 x’s plus four negative 1’s plus two negative x’s plus three 1’s.
So, an expression to represent the model could be
Now to simplify it further, combine the like terms as shown below,
Thus, the expression simplifies to,

b.
Answer to Problem 45IP
Explanation of Solution
Given:
The algebraic model
Calculation:
In order to write an expression to represent the given model, observe that the model contains eight negative 1’s plus three negative x’s plus two 1’s plus five negative x’s plus two x’s plus four 1’s.
So, an expression to represent the model could be
Now to simplify it further, combine the like terms as shown below,
Thus, the expression simplifies to,
