Prove algebraically that the sum of the squares of two consecutive intgers is always an odd number
musickatia [10]

Answer:

See below.

Step-by-step explanation:

Let's let our first integer be n.

Then, our second, consecutive integer must be (n+1).

We want to prove that the sum of the square of two consecutive integers is always odd.

So, let's square our two expressions and add them up:

(n)^2+(n+1)^2

Square. Use the perfect square trinomial pattern. So:

=n^2+(n^2+2n+1)

Combine like terms:

=2n^2+2n+1

Notice that the first term 2n² has a 2 in front. Anything multiplied by 2 is even. So, regardless of what integer n is, 2n² is <em>always</em> even.

Our second term 2n also has a 2 in front. So, whatever n is, 2n is also <em>always</em> even.

So far, 2n² and 2n are both even. Therefore, the sum of 2n² and 2n is <em>also </em>even.

Lastly, we have the constant term 1. It doesn't matter what n is, we know that (2n² + 2n) is definitely and is always even. So, if we add 1 to this, we will get an odd number.

Answer: #3 is y=-3/2x+1 (or 1 1/2x)

#2: -3/2

#1: 1

Step-by-step explanation:

To find the slope, make a right triangle with the line The 3 is the how many up, the 2 is the how many across. It is negative because it allows down to the right.

To find the intercept, look at where the line cross the vertical line. Which in this case, is 1
