Answer:

Step-by-step explanation:
The model shows that there are 40 tiles which were divided into 4 per group. This results into 10 groups. That is:

Therefore, the expression modeled by the arrangement of the tiles is 
Answer:

Step-by-step explanation:
Answer: A
Step-by-step explanation:
Given two points, say points
A and
B, we can use the slope formula to find the slop of the line:

If
A has coordinates of
(w,c) and
B has coordinates of
(y,z), we can find the slope.
![\frac{z-c[tex]y-w= \frac{z-x}{y-w} (x-c)](https://tex.z-dn.net/?f=%20%5Cfrac%7Bz-c%5Btex%5Dy-w%3D%20%5Cfrac%7Bz-x%7D%7By-w%7D%20%28x-c%29)
}{y-w} [/tex]
Now we can say that we can use the point slope form formula:

Now we can substitute
m for the slope, and use any points to plug in

and

.
Hope this helps! :^)
Answer:
-10
Step-by-step explanation:
You want to know the rate of descent in feet per second represented by a descent of 40 feet in 4 seconds.
<h3>Rate</h3>
The rate is the amount divided by the time:
-40 ft/(4 s) = -10 ft/s
The relevant integer is -10.
