(20 points will get brainliest) the height of a stack of dvd cases is proportinal to the number of cases in the stack. the height of 6 dvd cases is 114mm. write an equation that relates the height (y) of a stack of dvd cases and the number of cases (x) in the stack. what would be the height of 13 dvd cases

Step-by-step explanation:

Given the height of 6 DVD cases, you can know the height of a single DVD case, by dividing the total height, in the number of cases ( for this problem).

Now, knowing the height of a single DVD case (), you can think the expression in this way: If I already know the height of a single case, the height of any number of cases will be the result of multiplying the height of the case by the number of cases I want to stack.

As the problem states, x is the number of cases in the stack, so, multiply the height of a single case for the number of cases (x).

This will result in the expression:

To know the height of a stack of 13 cases, just replace x=13 in the equation you just figured:   , but don't forget the unit is mm, so the final result is 247 mm.

i believe the correct answer is option 4.principalities were small territories that were run by russian rulers.

which statement correctly defines principalities in northern asia in the 1200s? principalities were small territories that were run by russian rulers.

hope i could ! : )

yes   because as the functions are graphed they eventually will intersect unless otherwise
