D. -2a-b

Step-by-step explanation:

The additive inverse is found by multiplying the expression by -1.

-1(2a+b) = -2a -b . . . . matches selection D

Just a question- could you organize the data better? i just cannot tell which number are for which bakery. i will be happy to answer this question if you could do this for me! : )

Yes it is true that the additive inverse of the expression (2a + b) is (- 2a - b) where a and b are real numbers. This expression (- 2a - b) can also be written as [- (2a + b)]. I hope that this is the answer you were looking for and it has come to your help.

the highest percentage for deaths in construction from highest to lowest is as follows: falls, struck by objects, electrocution, and caught-in/between. these four are collectively known as fatal four.

in the case of falls, the type that is responsible for the overall highest death in the category is falls from roofs.

we know that

Additive inverse  is the number that one would need to add to equal zero

so

If $x+y=0$ -----> equation A

then

x and y are additive inverse

In this problem we have

$x=(2a+b)$

Find the value of y

Substitute the value of x in the equation A

$(2a+b)+y=0$

Subtract both sides $-(2a+b)$

$(2a+b)+y-(2a+b)=0-(2a+b)$

$y=-(2a+b)$

therefore

The additive inverse is  $-(2a+b)$

Subtract both sides $-(2a+b)$

$(2a+b)+y-(2a+b)=0-(2a+b)$

$y=-(2a+b)$

therefore

The additive inverse is  $-(2a+b)$

The additive inverse is equal to $-2a-b$

Step-by-step explanation:

we know that

The additive inverse of a number is equal to its opposite ( the sum of a number and its additive inverse is equal to zero)

so

we have

$2a+b$

Multiply by -1

$-1(2a+b)=-2a-b$

therefore

The additive inverse is equal to $-2a-b$
