1. For the data in the table, does y vary directly with x? If it does, write an equation for the direct variation. yes; y = 2.75xyes; y = 0.6875xyes; y = 1.375xno; y does not vary directly with x
Don't ask for answers.
i cant fail it again
We can not see the table as it is.
Take a printscreen of the question.
is this a test question? or is this a question for preparing for a test?
It is a test question. I told him we could not do it FOR him.
This is not a review question
reviews are fine then ... or at least thats the better answer of the two :)
Go ahead and take the wheel @amistre64
so this is a review right?
yes thats what i said i just cant fail
no; y does not vary directly with x As you can see.....y=2x, y=4x and y=8x are not true from the table.
can you help me for a bit or are you busy
to vary directly means to increase as it increases as x gets bigger, y gets bigger; so there is some direct variance at play if the ratio between x and y is the same for each point; then you will know the constant of variation looks to be a ration of 8/11 = x/y y = (11/8)x 1.3 ... id go the 3rd option
it took you that long to write wait no
k one sec
2. For the data in the table, does y vary directly with x? If it does, write an equation for the direct variation. yes; y = 2x yes; y = 4x yes; y = 8x no; y does not vary directly with x
no; y does not vary directly with x
hello you there?
yeah one sec sorry had to cook hot water
the first one is the answer.
for which one?
the one on top
and on the bottom is the 4th one
is that better for you?
