B. (9+4i)+(-1-7i)
This is because when you add the terms, the 9 becomes an 8 and the 4i becomes a negative 3i.
Step-by-step explanation:
-5=u+6
-5-6=u
-11=u
therefore , u= -11

Thickness of 1 quarter = 1.75 mm
So, 1000 quarters will be = 
= 1750 mm
So, a stack of 1000 quarters will be 1750 mm high.
Answer:
y=-x-5
Step-by-step explanation:
Slope is the x, since slope is equal to -1, x=-1. For the y intercept you simply add or subtract the number given to you, since it is -5 you would add a -5 to the end of the equation

5−(2w−8)=6w−9
Show Steps
Expand 5−(2w−8): −2w+13
−2w+13=6w−9
Subtract 13 from both sides
−2w+13−13=6w−9−13
Simplify
−2w=6w−22
Subtract 6w from both sides
−2w−6w=6w−22−6w
Simplify
−8w=−22
Divide both sides by −8
−8w
−8 =
−22
