Answer:
x = 3
Step-by-step explanation:
The angle bisector divides the segments either side of it proportionally. So, you have ...
x/4 = 2.25/3
x = 4·2.25/3 . . . . multiply by 4
x = 3
_____
Since DB = 3 and DA = 2.25, point D is clearly <em>not the midpoint</em> of AB.
Answer:
Differences between the actual Y values and the predicted Y values.
Step-by-step explanation:
The residuals represent the Differences between the actual Y values and the predicted Y values.
Residual is the difference between the measured value and the predicted value of a regression model. It is important to understand residuals because they show how accurate a mathematical function, such as a line, is in representing a set of data.
The answer is letter D.

You always begin by the Given equation, which is in this case:
y+

= 3x
To remove the fraction, you multiply the whole equation by 5:
5y + 1 = 15x
Then, you move the "15x" the left-side of the equation, changing it's sign
-15x + 5y +1 = 0
You move the "1" to the right side, changing it's sign
-15x + 5y = -1
So the correct answer is A :)
Hope it helped! ^^
