Answer:
- Student cannot determine proportionality because there is no y-intercept.
- Table and graph do not match
(Student does not realize they are based on two different people)
- Student computes x/y and not y/x (Ex. 3/27 or 2/18)
Step-by-step explanation:
-May not be able to determine Unit rate because (1, r) does not exist on the table.
-May answer “18” because it is the first point on the table.
-Unable to determine relationship between x and y values
Easy
V=LWH
V=x³+9x²+6x-16
L=x+2
H=x+8
W=?
so
x³+9x²+6x-16=(x+2)(?)(x+8)
x³+9x²+6x-16=(x+2)(x+8)(?)
x³+9x²+6x-16=(x²+10x+16)(?)
divide both sides by (x²+10x+16) or guess what ? is
(x-1)=?
width=x-1
B is answer
or you could have trial and erroed it, since you know they multiply to get the volume
what's the question ? is there something you don't understand

Because if you ever want to change it into a fraction or percent you will need to know the complete end of the number
