Answer:
(8,4)
Step-by-step explanation:
y and -y cancels out leaving you with "12x=96"
that simplifies to "x=8"
Then you substitute 8 into the "x" from either equation and y should equal 4
Answer: 
Step-by-step explanation:
Having the following equation given in the exercise:

You can solve for "a" following this procedure:
1. You can apply the Subtraction property of equality and subtract
from both sides of the equation:

2. Now you must subtract the terms on the left side of the equation. Notice that the Least Common Denominator is "d". Then:

3. Finally, you can apply the Multiplication property of equality and multiply both sides of the equation by "b". So, you get:

Answer:
Step-by-step explanation:
(2x^2+6x-8)(x+3)
2x^3+6x^2+6x^2+18x-8x+18
2x^3+12x^2+10x+18
Volume of the sphere = 4/3πr³
Volume of the sphere = 4/3 (π) (3)³
Volume of the sphere = 36π
Volume of the sphere = Volume of the cone
36π = 1/3π(3)²h
36π = 3πh
h = 36π ÷ 3π
h = 12

Answer: The height is 12 inches.

It would be 36 because ypu are adding 12.
