Is -9+7 the same as 7-n

nah the first equation dont got a variable in it and instead of 9 in the second one it has negative one

Step-by-step explanation:

Depends

Step-by-step explanation:

-9 + 7 = -2

7 - n = ?

Well the letter "N" could be of any value ( number ) therefore, no they are not the same.

Example:

IF -9 + 7 = -2 IS...

IF N = 1.

IS 7 - 1 equal to -9 + 7? No, because 7-1 = 6 and -9 + 7 = -2

IF N = 2.

IS 7 - 2 equal to -9 + 7? No, because 7 - 2 = 5 and -9 + 7 = -2

and so on...

However:

-9 + 7 and 7 - 9 are the same. I'm pretty sure it's the commutative property.

a line is an defined derm because it

a)contains an infinite number of points b) can be used to create other geometric shapes c)describes something that does not have width or depth d) is a term that does not have a formal definition. a line is an undefined term because it: contains an infinite number of points.

might be the correct answer will be question number 2
