For questions 4-5, how many solutions does the system have?

4. -4y+4=x
2x+8y=8
a. one solution
b. two solutions
c. infinitely many solutions
d. no solution

5. 6x+2=y
3y-18x=12
a. one solution
b. two solutions
c. infinitely many solutions
d. no solution

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.

it is true
