|dw:1442903340378:dw|

anonymous · Answer

Use variables of weight, W, and distance, D. (You will have to use one of your data points to find your constant of variation.) (1 point for the general form of variation, 1 point for the constant variation, and 1 point for the final equation)

welshfella · Answer

there is an inverse relationship between W and d. As w increases d decreases.
so W  = k/d  where k is a constant to be found

plug in one value of W and the corresponding value of d into the above equation then you can find the value of k.

welshfella · Answer

lets try the first 2 values
120 = k/100

now solve for k.

welshfella · Answer

do you follow this?
can you find what k is?

anonymous · Answer

im not too sure..would you multiply both sides by 100/1 to isolate the variable?
