Which number line represents the following statement?

x > -1

x < -1

x ≥ -1

x ≤ -1

x ≤ - 1

Step-by-step explanation:

The solid circle on the number line at - 1 indicates that x can equal - 1

The arrow pointing left indicates the values of x are less than - 1, thus

x ≤ - 1 represents the number line

687.09 dollars       happy now

step-by-step explanation: 6870

1857 times .63 equals 1169.91 subtract that from 1857 you get 687.09

18

step-by-step explanation:

draw the shape and you will see that f and k are actually at adjacent vertices (points of the hexagon that are neighboring).   so find the distance between (1,2) and (4,2).   that is easy since (1,2) and (4,2) is just a vertical distance to count, which is 3.   it is a regular polygon which means all sides are congruent.   you have 6 sides (hexa) so multiply 6 by 3 to receive 18.
