We can use the number line as a model to help us visualize adding and subtracting of signed integers. Just think of addition and subtraction as directions on the number line. There are also several rules and properties that define how to perform these basic operations.
To add integers having the same sign, keep the same sign and add the absolute value of each number.
To add integers with different signs, keep the sign of the number with the largest absolute value and subtract the smallest absolute value from the largest.
Subtract an integer by adding its opposite.
Examples:
4+(-8)=? Add a negative interger by moving to the left. Start at 4 and move 8 units to the left. 4+(-8)=-4
-4-(-3)=? To subtract an integer, add its opposite. Add the opposite of -3 , or 3. -4-(-3)= -4+3=-1

−9 1/2 + 8
What would the answer be
Answer:
-1 1/2
Step-by-step explanation:
Answer:
-1 1/2
Step-by-step explanation:
turn the fraction into a decimal 1/2 = 0.50
so, -9.50 + 8.00 you would subtract because in this case the negative is bigger than the positive so your answer will be negative.
-9.50
+ 8.00 = -1.50 convert .50 back into a fraction and your answer is -1 1/2.

Given the function g(x) = 8x − 2, compare and contrast g(−2) and g(4). Choose the statement that is true concerning these two values. The value of g(−2) is larger than the value of g(4). The value of g(−2) is the same as the value of g(4). The value of g(−2) is smaller than the value of g(4). The values of g(−2) and g(4) cannot be compared.
Answer:
The value of g(−2) is smaller than the value of g(4).
Step-by-step explanation:
To solve this, simply plug in the values in the given equation g(x)=8x-2.
g(-2)=8(-2)-2 -----> -18
g(4)=8(4)-2 ------> 30
here it is obvious that -18 is smaller than 30, therefore the value of g(−2) is smaller than the value of g(4).
Answer:
The value of g(-2) is smaller than the value of g(4).
Step-by-step explanation:
Substitute the values into the equation...
g(-2) = 8(-2) - 2
g(-2) = -16 - 2
g(-2) = -18
and,
g(4) = 8(4) - 2
g(4) = 32 - 2
g(4) = 30
So, as you can see the value of g(-2) is smaller than g(4).
Hope this helps :)

Write out the rule and fill in the empty boxes. Complete the function table.
Answer:
Input divided by 3 is output 28 and 38 are the outputs in the blank boxes
Step-by-step explanation:
33 divided by 3 is 11 126 divided by 3 is 42
[tex]\mathrm {Hey, there!}[/tex]
Let's solve your problem:
The answer to the question is the input is 3 times greater than the output.
Here, is my work below.
33 ÷ 11 = 3
126 ÷ 42 = 3
Therefore, the rule is the input is 3 times greater than output.
