Answer:
w = -1.266
Step-by-step explanation:
distribute the 5 by everything in the parenthesis and then bring everyhting down then you should have a regular equation to work w
0.05,reverse. if you have 0.05 and times it by 100 you get 5% and I divided 5% by 100 to get the answer, hope this helps! :)
The points represented are:

The domain is the set of all the inputs, i.e. the set composed by the x-coordinates of these points.
The range is the set of all the outputs, i.e. the set composed by the y-coordinates of these points.
This relation is a function, because you never map two outputs for the same input (i.e. you don't have two points with the same x-coordinate, but different y-coordinates).
