Answer:
If the expression is 2y+9x the answer is: 10x+12y
If the expression is 2y-9x the answer is -8x+12y
Step-by-step explanation:
You would combine all your x values:-4,9,9,-4 and that equals 10 then you would add your variable, so your x value is 10x.
You would then combine all your y values: 8,-2,8,-2, and that equals 12, then you would add your variable, so your y value is 12y.
Answer & Step-by-step explanation:
To find if they have a constant of proportionality of 12, use the following:

Divide y by the x value (x,y), and if the remaining equation is true, then that table has a constant of proportionality of 12.*
:Done
*Make sure you check all the values in a table. Sometimes only the first values will have k=12, while the others don't.
**The constant of proportionality is represented by <em>k</em>.
Hmmm A millimeter would be too big for that .
I think millionths of a meter would be about right. Micrometers.
6/10 rounding to the nearest half would be 1, not 0.
Reason for this: Here is a number line to help you!
|----|----|
Left line = 0
Middle line = 1/2
Right line = 1
Here is another rule!
0/10, 1/10, 2/10, 3/10, 4/10 = rounded to the nearest half would be 0
5/10, 6/10, 7/10, 8/10, 9/10, 10/10 = rounded to the nearest half would be 1.
So 6/10 rounded to the nearest half is 1.
