do you see a trend in the numbers for "y"?

OpenStudy (anonymous):

yes. 26

OpenStudy (anonymous):

you mean a constant difference of 26. this means that "x" and "y" are linearly related

you see, \(y=x\times26\)

its either 200 , 252 , 300 , or 312

good "x" represent the number of gallons and "y" represent the numbre of miles for that many gallons

so, the question gives you x=12 and asks you to find "y"

i think so ;o

thats what it is so, we plug in 12 for x \[y=12\times26=?\]

312 ?

4 years ago
OpenStudy (anonymous):

yep

4 years ago
OpenStudy (anonymous):

so thats the answer ?

OpenStudy (anonymous):

yes. the value for "y" when x=12 is the answer that is what you just calculated
