The value of this is -1 so the answer is B.
HOPE THIS HELPS!
HAVE A GR8 DAY;-)
Since, the number w and 0.8 are additive inverses.
A number 'a' is said to have an additive inverse '-a' if "a+ (-a)= 0".
Since, 'w' and '0.8' are additive inverses of each other such that 
Therefore, the value of 'w' should be '-0.8' so that
.
So, the value of 'w' is =0.8
Now, Refer to the attached image which represents the position of 0.8 , w ( that is -0.8) and the sum of 0.8 and w.
Sum of 0.8 and w = 0.8 + w
= 0.8 +(-0.8)
= 0.
Answer:
D
Step-by-step explanation:
A vertical line will have the steepest slope
So for this we're going to use this rule: a/b x c/d = ac/bd
simplify 1 x 1 to 1
simplify 4 x 4 to 16
4 x 1/16 to 4/16
simplify 4/16 to 1/4
simplify to 6/4
Lastly simplify
Answer: 3/2
*In decimal form it would be 1.5
