answer parts a, b,c

y=75x+50

y=600

x=3

Step-by-step explanation:

since at x=zero the y=50

then let y=nx+50

since at x=2 y=200, 200=2n+50, 2n=150, n=75

then y=75x+50

at x=8

y=75×8+50=600+50=600

at y=275

then 75x+50=275, 75x=225, x=225/75=3

i think this could be a possible answer (1 / 84) -1

good luck! : d

i believe the answer is the polygon, heptagon.
