Answer: -13.37
Explanation: I did it in decimals because I didn’t know if your assignment required fraction or decimal. 5 4/7= 5x7=35+4=39/7 so this means 5 4/7 is equal to 39/7. -2 2/5= -2x5=-10+2=-8/5. So it comes out to 39/7x-8/5.
True.. it should be from what i read about it on other sites.

Use Hooke's law... (just kidding)
Break down each force vector into horizontal and vertical components.



The resultant force is the sum of these vectors,

and has magnitude

The closest answer is D.
Left and right affect domain. (x)
Up and down effects range. (y)
So,
-2+5 (because the right of the number line is an increase)
7-2 (because you are decreasing by going down)
You are left with:
R'(3,5)
I hope this helps!
