Let x be the first number
X + 1 be the second number
So
(x+1)^2 – x^2 = 2017
X^2 + 2x +1 – x^2 = 2017
2x + 1 = 2017
2x = 2017 – 1
2x = 2016
X = 1008
X + 1 = 1009
Sum = 1008 + 1009 = 2017
Answer:
e= -5.41
Step-by-step explanation:
Hello!
In linear regression, a residual value is a distance between the observed values and the regression line.
The residual value (e) is calculated as the difference between the observed value (Y) and the predicted value (^Y).
e= Y - ^Y
e= 15.92 - 21.33 = -5.41
I hope it helps!
Answer:
As a model for representing fractions, the number line differs from other models (e.g., sets, regions) in several important ways. First, a length represents the unit, and the number line model suggests not only iteration of the unit but also simultaneous subdivisions of all iterated units. That is, the number line can be treated as a ruler.

Answer:
3.5
Step-by-step explanation:
Well its easiest to just plug in the answers and see like 2 times 3.5 is 7.
Another way is saying 7 divided by 2 is 3.5
then u check to make sure its the same for all the numbers.
Which it is because 21 divided by 6 is also 3.5 :)
