This question is easier than it seems. If there are 9 consecutive integers with the mean being 16, then 16 must be the median. So just add four on top and four below 16 to give you your range of 9 values, 12-20. 12+13+14+15+16+17+18+19+20=144, 144/9=16. So the mean of the first four numbers is (12+13+14+15)/4= 13.5. If you check, 13.5 is also the median of these four numbers.
I believe it is y= -x + 4
Y= 4 is perpendicular to the x- axis
The x- axis is the horizontal line, and the y- axis is the vertical line
Answer:
13w/3
Step-by-step explanation:
1/3 w+ 4w =( 1/3 + 4) w = (1+12)/3 w = 13/3w
