Answer:
11x^4
Step-by-step explanation:
The double negative automatically makes something positive. Your new expression is 5x^4 + 6x^4.
The only other thing you need to do is combine like terms by adding them together.
11x^4
We are given equation of total campsite charge

where
C is total campsite charge C (in dollars)
d is the number of days that the site is rented
so, here we will have
C is y-axis or dependent variable
d is x-axis or independent variable
we can find any two points and then we locate it
after that we can join them to get our graph
At d=0:


so, our point is (0,8)
At C=0:



so, our point is 
now, we can locate these points and then join it
<h2>Answer:</h2>
11 and 15
<h2>Explanations:</h2>
Given the arithmetic sequence -1, 3, 7 __, __, you are to find the next two terms of the sequence.
The nth term of an arithmetic sequence is given as;

where:
• a is the ,first term
,
• n is the ,number of terms
,
• d is the ,common difference
From the given sequence;
a = -1
d = 3 - (-1) = 7 - 3 = 4
For the fourth term, n = 4;

For the fifth term, n = 5;

Therefore the next two terms of the arithmetic sequence are 11 and 15.
Take the price of the cheese stick then divide that by the old price. you will get a decimal. New divided by old. You should have some decimal that is 1.something. If its a percent increase of 64 percent you'd have 1.64 as the decimal. good luck.
