-1 5/8 minus (-6 1/6)

4 13/24.

Step-by-step explanation:

-1 5/8 - (-6 1/6)

= - 1 5/8 + 6 1/6

= -13/8 + 37/6

LCM of 8 and 6 is 24:

= -39/24  + 148/24

= 109/24

=  4 13/24.

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.

f(x) = y

f(-3) = -5
