What is the sum of all the integers between -20 and 20

1 answer:

4 0

Answer:

Zero

Step-by-step explanation:

Because integers are equal in magnitude but opposite in sign, therefore they will cancel out each other leaving zero as answer.

$- 20 - 19 - 18 - 17 - 16 - 15.. - 1 + 0 + \\ 1 ..... + 15 + 16 + 17 + 18 + 19 + 20 \\ = 0$

The slope-intercept form:

$y=mx+b$

m - slope

b - y-intercept

We have the slope m = 4 → $y=4x+b$

and point (1, 6). Substitute:

$6=4(1)+b$

$6=4+b$ subtract 4 from both sides

$2=b\to b=2$

<h3>Answer: y = 4x + 2</h3>

1 of 10 is equivalent to 10% because 1/10 is .10 and .10•100% is 10% so the newspapers advertising is higher
