How do you graph and solve #|1+x|<8#?

1 Answer

Answer:

# -9 < x < 7 #

We can graph this on a number line by placing hollow dots over #-9, 7# (to indicate they are not part of the solution) and connecting the two dots with a line segment.

Explanation:

We can approach this question this way:

#abs(1+x)<8#

#-8<1+x<8#

# -9 < x < 7 #

We can graph this on a number line by placing hollow dots over #-9, 7# (to indicate they are not part of the solution) and connecting the two dots with a line segment.
