Step-by-step explanation:

Take the number as x

12x-40=7x+25

collect like terms

Which line graph correctly reflects the information in the frequency table?
bekas [8.4K]
<h3>Answer: Choice B</h3>

Explanation:

You can use Excel to make the graph, but other free options work just fine. I used LibreOffice to make the graph shown below.

Each point on the line graph represents a frequency for a given time value. The first point being 4 units high, means there were 4 customers at 8:00 AM. Then there were 6 customers at 9:00 AM, meaning the next dot has a height of 6. And so on.

The graph shown below matches with choice B.

What is the completely factored form of d4 − 81?
lilavasa [31]

For this case we must factor the following expression:

d ^ 4-81

Rewriting the expression:

(d ^ 2) ^ 2-9 ^ 2

We factor using the formula of the square difference:

a ^ 2-b ^ 2 = (a + b) (a-b)

Where:

a = d ^ 2\\b = 9

So:

(d ^ 2 + 9) (d ^ 2-9)

From the second term we have:

d ^ 2-3 ^ 2 = (d-3) (d + 3)

Finally, the factored expression is:

(d ^ 2 + 9) (d-3) (d + 3)

Answer:

(d ^ 2 + 9) (d-3) (d + 3)
