Answer:
19, 21, 23
Step-by-step explanation:
Let the first odd number be n.
Then the second, consecutive odd number will be (n+2).
And the third will be (n+4).
We know that they sum to 63. Hence, we can write the following equation:
Solve for n. Combine like terms:
Subtract 6 from both sides:
Divide both sides by 3:
Hence, the first odd number is 19.
Therefore, our sequence is: 19, 21, 23.
Note: If we get an even or non-integer value for our n, then there are no three consecutive odd integers that exists that sum to 63.
For this case we have that by definition, the equation of the line in the slope-intersection form is given by:
Where:
m: It is the slope of the line
b: It is the cut-off point with the y axis
We have two points through which the line passes:
We found the slope:
The slope is zero.
Thus, the equation is of the form:
We substitute one of the points and find b:
Finally, the equation is:
