Answer:

B. {day in a week that starts with the letter J}

Step-by-step explanation:

In the given situation if we go option B that the day in the week started from the letter J

Find the ordered pairs.<br><br> {Y=(x+1)^2-5<br> {Y=2x<br><br> PLEASE HELP!!!
vampirchik [111]

Answer:

\large \boxed{\sf \bf \ \ \text{The solutions are }(2,4) \text{ and } (-2,-4) \ \ }

Step-by-step explanation:

Hello, this is the same kind of question that you have already posted( brainly.com/question/17141820).

<em>I would suggest that you check my previous answer and try to apply the same logic here. When you try it if you have any question please let me know. It will be the more efficient way for you to learn how to solve it by yourself.</em>

<em>As I have already provided details for the previous question I will be more succinct here.</em>

Again we can write y = y and then we have to solve the following.

(x+1)^2-5=2x\\\\x^2+2x+1^2-5-2x=0\\\\x^2-4=x^2-2^2=(x-2)(x+2)=0\\\\x=2 \ \ or \ \ x=-2

The solutions are (2,4) and (-2,-4)

Hope this helps.

Do not hesitate if you need further explanation.

Thank you

the sum of any n consecutive integers is always equal to 100 less than the sum of the next n consecutive integers. Find n.
Salsk061 [2.6K]

When we have a given number k, the consecutive number to k will be (k + 1), the next consecutive will be (k + 2), and so on.

With this, we can find that the value of n is 100.

So here we have n consecutive numbers, let's assume we start with the number k, then the sum will be:

k + (k + 1) + ... + (k + n - 1)

Now we know that this is 100 less than the sum of the next n consecutive numbers.

For the next n consecutive numbers we need to start at k + 1, then we get:

(k + 1) + (k + 2) + ... + (k + n - 1) + (k + n)

If we take the difference we will get:

((k + 1) + (k + 2) + ... + (k + n - 1) + (k + n)) - (k + (k + 1) + ... + (k + n - 1)) = 100

As you can see, there are a lot of terms that are in both parentheses, then when we do that difference a lot of them cancel out.

So we will et:

((k + 1) + (k + 2) + ... + (k + n - 1) + (k + n)) - (k + (k + 1) + ... + (k + n - 1))

= (k + n) - k = k + n - k = n

And we knew that this difference must be equal to 100, then we have:

n = 100

We just found the value of n.
