Answer:
Step-by-step explanation:
<u>Exponents Properties</u>
We need to recall the following properties of exponents:
We are given the expression:
We need to express the following expression in terms of n.
It's necessary to modify the expression to use the given equivalence.
Recall 
. Thus:
Applying the property:
Substituting the given expression:
Or, equivalently:
4n - (7-6n)
4n -7 +6n (multiply minus to 7-6n)
10n -7 is the answer
Answer:
D, because for every x, the 3 slowly become slower. IF the thing that is being taken to the power of x is less than one it is a decay
Given:
c = cost
p = people
Spent $300
Formula: c=5p+215
Solving for how many people (p)
C=5P+215
(300)=5P+215 (Subtract 215 on both sides)
85=5P (Divide by 5 on both sides)
17=P
The answer is 17. 17 people can afford to host a birthday party.
The factored version of the above statement would be 5(x + 4)
In order to find this, you need to find the greatest common factor of the two coefficients. First, list the factors of each.
Factors of 5: 1, 5
Factors of 20: 1, 2, 4, 5, 10, 20
Since the highest that exists in both lists is 5, we can divide both terms by 5 and pull it out of the parenthesis like this:
5(w + 4)
Which is your final answer
