Answer:
3+c < -29 or c+3 < -29 because of communitive property
Step-by-step explanation:
First, the sum means addition, you could write 3+c or c+3 because addition is communitive property.
Then the sum is less than -29 so we need to use the less than symbol which is this symbol: <
Now write the inequality! 3+c < -29
Answer:
Yes, *2
Step-by-step explanation:
The second figure is exactly half of the first figure
Answer: (14, 5)
===========================================================
Explanation:
Translating 5 units to the right means x becomes x+5. Whatever the x coordinate is, we add on 5.
Translating 4 units down means we go from y to y-4.
Overall, the point (x,y) becomes (x+5, y-4).
We can write the compact notation 
So for the specific point given, we can say:

The point (9,9) shifts to (14, 5)
No, it is a linear function.
It can increase the field because of the loops around the electromagnet like a conductor which can amplify the magnetic field making it go further
