How do i add a negative integer and a postive integer

See below.

Step-by-step explanation:

Step 1.

Take the absolute value of the negative number.

Now both numbers are positive.

Step 2.

Subtract the smaller positive number from the larger positive number.

Step 2.

The sign of the answer is the same sign as the number with the larger absolute value.

To add a negative integer and a positive integer, just think of changing the negative integer to a positive one and subtracting this from the original.

Step-by-step explanation:

To add a negative integer and a positive integer, just think of changing the negative integer to a positive one and subtracting this from the original.

For example: 7 + -5. If you look, You are adding 5 negatives to a 7: you are subtracting 5 from 7. Subtracting a negative integer is the same as adding.

6 - -7, for example. You are subtracting 7 negatives from 6, or adding 7 to 6.

step-by-step explanation:

the formula for the constant of variation is

y= kx

divide each side by x

y/x =kx/x

y/x =k

we know a and y

1.   y/x = k

4/1 =4

check the other values to make sure they are the same

8/2 = 4   12/3 =4   and 16/4 =4  

the constant of variation is 4

2.   y/x = k

3/1 =3

check the other values to make sure they are the same

6/2 = 3   9/3 =3   and 12/4 =3  

the constant of variation is 3
