What are the asymptotes of the following graph?
allochka39001 [22]

Answer:

  y = ±(1/3)x

Step-by-step explanation:

The asymptotes of this hyperbola will contain the diagonals of the green rectangle. The green rectangle at the center of this hyperbola has corners that have a run from its center of 3 for a rise of ±1, so the slope of the line from its center to the corner is rise/run = ±1/3. The center is at (0, 0), so the equations of the asymptotes are

  y = ±(1/3)x

crimeas [40]

Answer:

55+19.50m=250

Step-by-step explanation:

55 is the intial fee it doesn't have to be multiplied by anything.

19.50 is monthly it is multiplied by how many months she is going to be there. the amount of months is unknown so you use a variable I chose m for months or monthly.

it will be set equal to 250 because that is the amount of money that she has to spend.

I hope this helps I am sorry if it is wrong
