23 + 8m + 4n - 5m - 27​
mylen [45]

Answer:

-4 + 3m + 4n

Step-by-step explanation:

In this question, you are combining like terms, meaning doing equations to numbers that fit with only each other.

<u>So we should start on the number without variables:</u>

23 and 27

<u>Match them up together and you should find your first equation:</u>

23 - 7

==> -4

So we should have  -4  +  8m  +  4n  -  5m

Now we should combine the numbers with the variable of m:

8m and 5m

<u>Match them up together and you should find your first equation:</u>

<u></u>

8m - 5m

==> 3m

So we should now have -4  + 3m  + 4n

<u></u>

<u>Since there are no other variables of n, we are all done:</u>

<u>-4  + 3m  + 4n  is  your  final  answer </u>

Which translation for: y = (x+3)^2+4<br><br> If you can't see the picture zoom in.
Savatey [412]

Answer:

The answer is B.

Step-by-step explanation:

The original graph of y = x^2 has a vertex at (0,0)

The formula for graph translations is y = (x-#)^2+#

The number inside the parentheses is a horizontal translation.

So, we are given y = (x-(-3))^2+#

The vertex of the graph moves 3 points left, since the number is negative (-3).

The number at the end of the equation is a vertical translation.

So, we are given y = (x+3)^2+4

The vertex of the graph moves 4 points up, since the number is positive (4).

The new vertex is at (-3,4)

The price for 11 ballpoint pens is $11.77. Which of the following represents the same price per pen? A. 4 pens for $4.44 B. 5 pe
Harrizon [31]
First we need to know how much each pen costs.  So we take 11.77 and divide it by 11.  That gives us 1.07 per pen.  So answer choice A has 4 pens for 4.44, so we need to multiply 1.07 x 4.  That gives you 4.28, so we know that isn't the correct answer.  For option B, we need to multiply 1.07 x 5.  That is 5.35, so that also can't be the answer.  For C, we need to do 1.07 x 6, and that gives us 6.42.  So we know the correct answer is option C.

Please help me with the question. Will mark brainliest.
Inessa05 [86]

Step-by-step explanation:

A.) Ok, so the mean price for Southtown is 72,800.

And the mean price for middle town is 54,900

So Southtown has the higher mean price.

Explanation:

To find the mean. You must first add up all the numbers, then divide the total by how many numbers you added up.

72,000 + 50,000 + 68,000 + 93,000 + 81,000 = 364,000

Then,

364,000/ 5 = 72,800

B.) It is 17,900

Explanation:

72,800 - 54,900 = 17,900

Hope this helps you out!!! : )
