y=x+8
y=4x+5

(1, 9 )

Step-by-step explanation:

Given the 2 equations

y = x + 8 → (1)

y = 4x + 5 → (2)

Substitute y = 4x + 5 into (1)

4x + 5 = x + 8 ( subtract x from both sides )

3x + 5 = 8 ( subtract 5 from both sides )

3x = 3 ( divide both sides by 3 )

x = 1

Substitute x = 1 into either of the 2 equations for corresponding value of y

Substituting in (1)

y = 1 + 8 = 9

Solution is (1, 9 )

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.
