What is the value of f(-3) in F(x)=0.3x+13

12.1

Step-by-step explanation:

Basically, everywhere you see an x, you should put -3 in the value.

F(x)=0.3x+13

f(-3)= 0.3(-3) + 13

= -0.9 + 13

= 12.1

step-by-step explanation:

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.
