Such a sum is always rational.
Yes.
The sum of two consecutive integers will always be an odd number.
The sum of two polynomials is always a polynomial. Therefore, it follows that the sum of more than two polynomials is also a polynomial.
11 and 11. In general, you can write an equation (or two equations), and solve with the quadratic formula, to solve this type of questions.
yes
Yes. You would have to multiply to change it.
Well, it sounds like a plausible statement, and maybe it would be true . But we haveno idea what the graph of two functions is.Perhaps you could graph the sum of two functions, or the difference of two functions,or their product, or their quotient. We believe that if the original two functions areboth continuous, then their sum and difference would also be continuous, but theirproduct and their quotient might not necessarily be continuous. However, we stilldon't know what the "graph of two functions" is.
You should always use the vertex and at least two points to graph each quadratic equation. A good choice for two points are the intercepts of the quadratic equation.
The sum of two odd numbers is always even.
No, the sum of two vectors cannot be a scalar.
No, the sum of two consecutive numbers is always an odd number, and is not divisible by two.
Such a sum is always rational.
Yes the sum of two integers will always be an integer.
Yes, by definition, the sum of two integers is always an integer. Likewise, the product and difference of two integers is always an integer.

the sum of two negative integers is ALWAYS negative
