I am trying to figure out if these problems are Direct Variation, Inverse Variation, or Neither. Could someone please check my answers?
r= 9/t Inverse
z= -0.2/t Inverse
suppose I write
c = e/-4 as c = (-1/4) e
u = l/18 as us = (1/8)l
now what do you think?
Inverse for both I think. Right?
No, both direct, the variable is in the numerator.
I wrote it the way I did, to point that out to you.
Notice that to be an inverse variation, the variable must be in the denominator.
