Raj and Carly started at the same point and walked backwards in the same direction. The distance that Raj walked backwards can be represented as -x. The distance that Carly walked backwards can be represented as -y.

a) Write an equation that can be used to find the absolute value of the distance (d) between Raj and Carly.

b) What is the distance between Raj and Carly, if Raj walked 9 1/2 yards and Carly waked backwards 15 1/2 yards?

amistre64 · Answer

can we assume that they started at 0?

calculusxy · Answer

Sure?

amistre64 · Answer

the waling backwards nensense had me confused if i was reading stuff correctly

amistre64 · Answer

if we take their final positions, the distance between them is ... well the difference between them

if one walks 3 feet, and the other walked 7 feet, both in the same direction

then the distance between them is |3-7|  or |7-3|  right?

calculusxy · Answer

Yeah

amistre64 · Answer

then what would you detemrine our equation to be?

calculusxy · Answer

|-x - (-y)| =d

amistre64 · Answer

yeah, that works for me

calculusxy · Answer

And then for part B, would it be:
-9.5 -(-15.5)=6 yards 
?

amistre64 · Answer

and for the record, saying:  the absolute value of the distance is double speak since distances can only be unsigned.

amistre64 · Answer

yes, but dont forget to wrap it in your || bars

Okay thanks :)
