What is the results of adding these two equations?<br> 6x+2y=-2<br> 3x-2y=-5
Bess [88]

Answer:

x=-7/9, y=4/3. (-7/9, 4/3).

Step-by-step explanation:

6x+2y=-2

3x-2y=-5

-----------------

9x=-7

x=-7/9

6(-7/9)+2y=-2

-42/9+2y=-2

2y=-2-(-42/9)

2y=-2+42/9

2y=-18/9+42/9

2y=24/9

y=(24/9)/2

y=(24/9)(1/2)

y=24/18

y=4/3

</span>The volume of a cone= π r^2 h/3 = π (9)(8)/ 3 = 24 π

Total volume = 18 π + 24π = 42π = 42 x 3.14 = 131.9 cm^3
