Which number line models represents 1+ (-3)

D graph would represent  1+ (-3).

Step-by-step explanation:

Given : 1 + (-3 )

To find  : Which number line models represents 1+ (-3).

Solution : We have given that 1 + (-3 ).

1 + (-3 ) = 1 -3  

⇒ -2.

We have start from 1 and will move left 3 unit ( for - sign) and finally get -2.

Therefore, D graph would represent  1+ (-3).

step-by-step explanation:

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.
