What do the digestive and excretory systems have in common?

The excretory system and respiratory system both get rid of waste products. The excretory system disposes of all food not absorbed by the body, and any foods that the digestive system couldn't break down. The respiratory system removes carbon dioxide, a waste product of the cell, from the circulatory system.

Step-by-step explanation:

Both get rid of waste

Step-by-step explanation:

none

option c) graph of line going through 1, 4 and 3, 10

step-by-step explanation:

let y equal to margo's coin collection

let x equal to number of years

at the begining x=0, y=1 → point=(x,y)→point=(0,1)

she adds 3 coins per year, then y=1+3x

at x=1, y=1+3(1)=1+3→y=4→point=(x,y)→point=(1,4)

at x=3, y=1+3(3)=1+9→y=10→point=(x,y)→point=(3,10)

the graph of line going through (1, 4) and (3, 10), then the option c is the correct.
