Answer:
x=-1, y=-7
Step-by-step explanation:
8x-2y=6
3x+3y=-24
Multiplying the topmost equation by 3/2:
12x-3y=9
3x+3y=-24
Adding the two equations together:
15x=-15
x=-1
Plugging this back into a previous equation:
8(-1)-2y=6
-8-2y=6
-2y=14
y=-7
Hope this helps!

Given
The volume of a sphere is
The volume of sphere with radius r is given by
Insert the values
Therefore, the radius is
I don't know what the ordered pairs are here, but anyone that doesn't end with a three. Example, (1,3) is on the graph. so is (27, 3) y, will always be three:)
