Answer:

  (x, y) = (-2, 1)

Step-by-step explanation:

Equate the two expressions for y.

  -5x -9 = 2x +5

  -14 = 7x . . . . . . . .add 5x-5

  -2 = x . . . . . . . . . divide by 7

Then ...

  y = 2(-2) +5 = 1

The solution is (x, y) = (-2, 1).

Flura [38]

V=1024 pi m^3 and v=250 pi m^3
the similarity ratio of the smaller to larger similar cones is 
k= V/v=1024 pi m^3/250 pi m^3= 4.096
the great cone is 4.096 times of the small cone (in volume)
