Answer:
Given f(-2)
= -5 -7(-2)
= -5+14
= 9
Thus f(-2) of f(x)= 5-7x is 9
Answer:
(x+5^3 is the answer of this question
For this case we have the following variable:
p: cost of the item that Arthur wants to buy before tax
The expression for the 6% tax is given by:
Or equivalently:
Therefore, two different expressions for the total cost are:
Expression 1:
Expression 2:
To prove that they are equal, suppose that the item costs $ 100:
Expression 1:
Expression 2:

Since the cost is the same, then the expressions are the same.
Answer:
Two different expressions that model the problem are:
Answer:
14
Step-by-step explanation:
105 and (6x-21) the same. So you do 105 minus 21, then divide that by 6.
