A proportional relationship between two quantities is one in which the two quantities vary directly with one and other. If one item is doubled, the other, related item is also doubled
So A can already be eliminated since you're adding 1 to X and adding 12 for Y
OpenStudy (sagewilson):
Now let's look at B
X: 8 *2 16 *2 24 *2 32
Y: 24 +12 48 +12 72 +12 96
So NO.
OpenStudy (sagewilson):
Okay, none of these seem to be a proportional relationship

om xD

OpenStudy (anonymous):
48 and 27
OpenStudy (anonymous):
and i think its a ?
RhondaSommer (rhondasommer):
look at a. when you multiplied 9; did you get the answer that was below that
A.
x 8 9 10 11
y 24 48 72 96
B.
x 8 16 24 32
y 24 48 72 96

then its b
RhondaSommer (rhondasommer):
no. your doing this yourself. i am not giving you the answer
OpenStudy (anonymous):
yeah but from what you said its either gonna be a or b i really think a
RhondaSommer (rhondasommer):
LOOK AT WHAT YOU DID
8 to 24 means you multiply by 3.
9 to 48 is NOT multiply by 3
16 to 48 IS multiply by 3
SO WHICH ONE COULD IT POSSIBLY BE?
OpenStudy (anonymous):
so its B?!
