The equation in y = mx+b form is y = -450x+2745
where,
x = number of hours that have passed by
y = distance to destination in miles
The y intercept is 2745 since this is the initial starting y value, aka the starting distance. Therefore b = 2745.
The slope is -450 or -450/1 since for each hour, the distance goes down by 450. You can think of it as
slope = (change in y)/(change in x)
slope = (change in distance)/(change in time)
slope = (-450 miles)/(1 hour)
slope = -450
The steps in the patterns A and B form a sequence
The attached diagram represents dots in patterns A and B
<h3>How to draw the diagrams</h3>
For pattern A, we have:
Step 2 = 10 dots
Increment of 3 dots in each step
This means that:
Step 0 = 4 dots
Step 1 = 7 dots
Step 2 = 10 dots
Step 3 = 13 dots
For pattern A, we have the following rule
![T_n =2n^2 + 1](https://tex.z-dn.net/?f=T_n%20%3D2n%5E2%20%2B%201)
When n = 0 to 3, we have:
![T_0 =2(0)^2 + 1 =1](https://tex.z-dn.net/?f=T_0%20%3D2%280%29%5E2%20%2B%201%20%3D1)
Step 0 = 1 dot
![T_1 =2(1)^2 + 1 =3](https://tex.z-dn.net/?f=T_1%20%3D2%281%29%5E2%20%2B%201%20%3D3)
Step 1 = 3 dots
![T_2 =2(2)^2 + 1 =9](https://tex.z-dn.net/?f=T_2%20%3D2%282%29%5E2%20%2B%201%20%3D9)
Step 2 = 9 dots
![T_3 =2(3)^2 + 1 =19](https://tex.z-dn.net/?f=T_3%20%3D2%283%29%5E2%20%2B%201%20%3D19)
Step 3 = 19 dots
Next, we draw the diagrams of both patterns (see attachment)

Answer:
in neighbourhood q the total number of people in the nine families I higher than that in neighbourhood s because of we add up the number of people in the families in neighbourhood q we get a total of 35 yet we have a total of only 27 people in the nine families in neighbourhood s
hope that helps ❤
The answer is letter A.
In the paragraph, only 20% of the customers who voted highly returned. From this, we can only say that some of those people came back. Most means a majority of the population and some means a minority.
Also, we can't say C or D because we do not have any information regarding customers who voted badly. C says that high rating make people come back, but we do not have any information on the people who voted mediocre. We can not say C. D says that customers who come back will be high rating customers. We do not know if any customers who voted low came back, so we are unable to say D.
Answer:
There are 392 students in the seventh grade.
Step-by-step explanation:
Let us assume that there are x number of students in the seventh grade.
Now, 3/8 of the seventh grade students were taking Advanced math at the beginning of the year, but seven dropped out by the end of the year.
So, after the end of the year there were
number of students taking advanced math.
So, as per given condition, ![(\frac{3}{8}x - 7) = 140](https://tex.z-dn.net/?f=%28%5Cfrac%7B3%7D%7B8%7Dx%20-%207%29%20%3D%20140)
⇒ ![\frac{3}{8}x = 147](https://tex.z-dn.net/?f=%5Cfrac%7B3%7D%7B8%7Dx%20%3D%20147)
⇒ x = 392
Therefore, there are 392 students in the seventh grade. (Answer)
