An integer is a number that comprises of natural numbers like 0,1,2,3,4... so on and negative whole numbers like -1,-2,-3 and so on.
Multiplication Rules:
1. Product of two positive integers is always POSITIVE.
Eg: 
2. Product of two negative integers is always POSITIVE.
Eg: 
3. Product of a negative integer and a positive integer is always NEGATIVE.
Eg: 
Quotient Rules:
1. Positive integer divided by a positive integer is always POSITIVE.
Eg: 
2. Positive integer divided by negative integer or negative integer divided by a positive integer is always NEGATIVE.
Eg: 
3. Negative integer divided by a negative integer is always POSITIVE.
Eg: 
If the store has 35 total gallons, 2/3,14 gallons, of that is outdoor. Since you are looking for indoor, you subtract the outdoor gallons from the total amount which equal 3/5 or 21. Then you multiply 21•22=$462
Answer:
im assuming that 2117 is 21:17
25:6
21:17
7:12
Step-by-step explanation:
Answer:
4. obtuse
5. obtuse
6. acute
7. acute
8. obtuse
Step-by-step explanation:
4. This angle is greater than a right angle (because it extends farther than one), so this is obtuse.
5. This angle is greater than a right angle, so this is obtuse.
6. This angle is smaller than a right angle (because it extends less than one), so this is acute.
7. This angle is smaller than a right angle, so this is acute.
8. This angle is greater than a right angle, so this is obtuse.
So firstly, we have to find f(x) when x = 8 and x = 0. Plug the two numbers into the x variable of the function to solve for their f(x):
Now that we have their y's, we can use the slope, aka average rate of change, formula, which is 
. Using what we have, we can solve it as such:
In short, the average rate of change from x = 0 to x = 8 is 5/21.
