Answer:
25 boxes.
Step-by-step explanation:
We have the inequality:
190 + 60x ≤ 1740 where x = the number of boxes of books.
60x ≤ 1740 - 190
60x ≤ 1550
x ≤ 25.83.
Answer:
B. 
Step-by-step explanation:
Well lets graph the following equation first,
H(x) = -.011(x - 82)^2 + 75
Then lets graph all the other equations.
Look at the image below↓
So A.
The purple line does not go farther or higher,
so A. is incorrect
B.
The black line goes higher and farther,
meaning it is correct.
C.
The red line goes farther but not higher.
So it is incorrect
D.
Again the blue line does not go farther of higher.
So its wrong.
<em>Thus,</em>
<em>answer choice B. </em>
<em>is correct.</em>

<em>Hope this helps :)</em>
Answer:
63 Lights
Step-by-step explanation:
First you can convert the feet to inches:
The length of decorative lights is 264 inches
You can then subtract 16 from 264
264 - 16 = 248
248/4 = 62
Adding one extra light at the end of the string of decorative lights you can get 63 lights on the string
Answer:
Question 9:
The product is irrational
Question 10:
20
10
Step-by-step explanation:
Intersection of the first two lines:

Multiply the first equation by 4 and the second by 5:

Subtract the two equations:

Plug this value for y in one of the equation, for example the first:

So, the first point of intersection is 
We can find the intersection of the other two lines in the same way: we start with

Use the fact that x and y are the same to rewrite the second equation as

And since x and y are the same, the second point is 
So, we're looking for a line passing through
and
. We may use the formula to find the equation of a line knowing two of its points, but in this case it is very clear that both points have the same coordinates, so the line must be 
In the attached figure, line
is light green, line
is dark green, and their intersection is point A.
Simiarly, line
is red, line
is orange, and their intersection is B.
As you can see, the line connecting A and B is the red line itself.
