Answer:
18y(2)-9y-2
Step-by-step explanation:
18y(2)-12y+3y-2
18y(2)-9y-2
The weight average of the coordinates is 7
<h3>How to determine the weight average?</h3>
The given parameters are:
Coordinate 5 has a weight of 1
Coordinate 8 has a weight of 2
The weight average is then calculated as:
Weight average = Sum of (Weight * Coordinate)/Sum of Weights
So, we have:
Weight average = (5 * 1 + 8 * 2)/(1 + 2)
Evaluate the quotient
Weight average = 7
Hence, the weight average of the coordinates is 7
