Subtracting from both sides leaves you with . Since subtraction can be written as addition (adding the opposite), the addition property of equality. If two expressions are equal to each other and you add the same value to both sides of the equation, the equation will remain equal.
The goal in solving an equation is to get the variable by itself on one side of the equation and a number on the other side of the equation. ... Performing the same operation on both sides of an equation does not change the validity of the equation, or the value of the variable that satisfies it.
Let these there numbers be assigned to variables x, y and z. Since you want to find the sum, add all numbers. However, the sum has boundaries between 10 and 20. Therefore, you will have to use inequality symbols. The two addition equations that could be formulated are:
<em>x+y+z > 10</em>
<em>x+y+z < 20</em>

Divide the diameter by 2 to get the radius and then plug into cone volume pi*r^2*h/3 which is a bit under 160 so the answer is A
Answer:
g(x) approaches negative infinity
Step-by-step explanation:
g(x) = -x² + 2x + 4
limit at g(x) approaches infinity = -(∞)² + 2(∞) + 4 = -∞
I can't solve for f(x) because you didnt give me f(x)
