Answer:
the solution is (-3, -2)
Step-by-step explanation:
Please, separate your equations with a (;) or a (.). Better yet, write only one equation per line:
y=2x+4
3x−6y=3
Substitute 2x + 4 for y in the second equation:
3x - 6(2x + 4) = 3, or
3x - 12x - 24 = 3
Combining like terms, we get -9x = 27, and so x = -27/9, or x = -3.
Since we know that y=2x+4, we replace x in this equation with -3 and calculate y:
y = 2(-3) + 4 = -2
Then the solution is (-3, -2).
Answer:
14130 yd^3
Step-by-step explanation:
The volume of a sphere is
V = 4/3 pi r^3
The diameter is 30 so the radius is d/2 = 30/2 = 15
V = 4/3 pi (15)^3
V = 4500 pi
Letting pi = 3.14
V = 14130 yd^3
