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: 
Answer:
Yes
Step-by-step explanation:
Plug in (-1 , -2) in the LHS of the equation.
2x - 3y = 2*(-1) - 3*(-2)
= -2 + 6
= 4 = RHS
So, (-1 , -2) is a solution
Part A:
Yes, the data represent a function because there is at least one x-value for every y-value.
Part B:
When x=6 in the input-output table, y=6 as well. When x=6 in the relation f(x)=2x+16, f(x)=2(6)+16=28. The equation has a greater value when x=6.
Part C:
Set f(x) equal to 40 in the equation:
40=2x+16
Solve for x:
2x=24
x=12
x=12 when f(x)=40
Answer:
<u>D) x² - y = 10x + 25 + y</u>
Step-by-step explanation:
A relation only becomes a function if each x-value only has a single y-value as the answer.
<u>Evaluating</u>
- A and B cannot be the answers as each value will get 2 answers
- C will also not be the answer as y² means at least 2 answers will be given
- <u>D</u> is the best option as each inputted x-value will get an answer of a single y-value

B
