Answer:

-16n - 41

Step-by-step explanation:

To simplify the equation, you need to get rid of the parentheses by multiplying the numbers outside the parentheses to the numbers inside. Then, you can combine the similar terms.

2(-n - 3) - 7(5 + 2n)                         <---- Original equation

-2n - 6 - 7(5 + 2n)                           <---- Expand first parentheses by mult.

-2n - 6 - 35 - 14n                            <---- Expand second parentheses by mult.

-16n - 6 - 35                                    <---- Combine terms with "n"

-16n - 41                                          <---- Combine whole numbers

Consider the line y=10 x -1 and the point P=(2,0). (a) Write the formula for a function d(x) that describes the distance between
LuckyWell [14K]

Answer:

the formula for a function d(x) that describes the distance is d(x)=\sqrt{101x^{2}-24x+5}

Step-by-step explanation:

We are going to define final point P_{f}=(2,0), and initial point P_{i}=(x,y)=(x,10x-1), then we can use d=\sqrt{(x_{f}-x_{i})^{2}+(y_{f}-y_{i})^{2}}, so we obtain d(x)=\sqrt{(2-x)^{2}+(0-(10x-1))^{2}}, by developing it d(x)=\sqrt{(2-x)^{2}+(0-(10x-1))^{2}}\\d(x)=\sqrt{4-4x+x^{2}+(1-10x)^{2}}\\d(x)=\sqrt{4-4x+x^{2}+1-20x+100x^{2}}\\d(x)=\sqrt{101x^{2}-24x+5}\\

This formula describes the distance between those two points and involves x

What is the mean of the data set? {32, 33, 34, 34, 36, 38, 38, 38, 40, 42}
Sphinxa [80]
Add all the numbers:

32 + 33  34 + 34 + 36 + 38 + 38 + 38 + 40 + 42 = 365

There are 10 numbers.

Divide:
Total by how many numbers there are

Total = 365
Numbers = 10

365 / 10 = 36.5

The mean is 36.5

Hope this helped☺☺

A company buys pens at the rate of $5.50 per box for the first 10 boxes, $4.50 per box for the next 10 boxes, and $3.50 per box
marusya05 [52]

So it is really easy to solve firstly we can see how much does the first 10 boxes make which makes around 55$ obviously. Secondly 45$ for the next 10 boxes.

So for now we can simply calculate that we have spent around 100$ which means 20 boxes. The remaining money left is 77$ so we can buy 77/3.5 = 22 only 22 boxes with that money. Hence a total of 42 boxes.

A certain brand of golf balls comes in packs of 24. Each pack has three yellow golf balls in it. Willam orders 360 golf balls on
iogann1982 [59]

Start by taking the total number of golf balls, 360, and dividing it by how many golf balls come in each pack, to find the number of packs.


360 ÷ 24 = 15


So there are 15 packs, each with 3 yellow golf balls.


15 · 3 = 45


Meaning 45 of the golf balls would be yellow
