Answer:
B
Step-by-step explanation:
just think logically about it.
you take f(x) (which stands for the result value y, you know that), do not change f(x) in any way but add finally 5 to every y value created.
there is no other effect than moving the whole f(x) curve up by 5 units, because every y value is now bigger by 5 units.
U = vw + z
vw + z = u |subtract z from both sides
vw = u - z |divide both sides by w
v = (u - z)/w
Let's look at our equation,
<span>p÷7
We must look at all our options before selecting one of them.
Can the answer be A?
</span><span>Jayna does not know how many pages she needs to read. She knows she has already read for 7 days.
</span><span>
No that would not work,
We would have subtraction. It would look like this.
p-7.
How about B?
</span><span>Jayna does not know how many pages she needs to read. She knows that she has 7 days to finish her book.
</span><span>
That would actually work. This is how our equation would look.
p</span>÷7.
<span>It matches the expression.
Before we make that our final answer, we should check everything else.
Here is C
</span><span>C.
Jayna does not know how many days she has to finish reading. She knows she has to read 7 more pages.
</span>
That would not work.
How about D?
<span>D.
Jayna does not know how many pages she has already read. She knows she has to read 7 more.
</span>
D is also incorrect. It would not work at all.
That means our final answer is:
<span>B.
Jayna does not know how many pages she needs to read. She knows that she has 7 days to finish her book.

I hope that helped! :)
<h3>Solution:</h3>
<u>We know that:</u>
![1. \space\ V_{Rectangular \space\ prism} = 10 \text\] units^{3}\\\\2. \space\ L_{Small \space\ cube} = \frac{1}{2} \space\ units\\\\ 3. \space\ V_{Small \space\ cube} = L ^{3}](https://tex.z-dn.net/?f=1.%20%5Cspace%5C%20V_%7BRectangular%20%5Cspace%5C%20prism%7D%20%20%3D%2010%20%5Ctext%5C%5D%20units%5E%7B3%7D%5C%5C%5C%5C2.%20%5Cspace%5C%20L_%7BSmall%20%5Cspace%5C%20cube%7D%20%3D%20%5Cfrac%7B1%7D%7B2%7D%20%5Cspace%5C%20units%5C%5C%5C%5C%203.%20%5Cspace%5C%20V_%7BSmall%20%5Cspace%5C%20cube%7D%20%3D%20L%20%5E%7B3%7D)
<u>Step-1: Find the volume of the small cube.</u>
<u>Step-2: Divide.</u>
Hence, 80 cubes can be fit in the <u>rectangular prism.</u>
