Answer:
transformations are used to to graph the linear function in the form of f(x)=mx+b f ( x ) = m x + b. google says to "Graph f(x)=x f ( x ) = x . Vertically stretch or compress the graph by a factor |m|. Shift the graph up or down b units."
I assume the rug is rectangle.
The area of rectangle is width (W) multiply by hight (H)

The rug is

meters wide
What questions I mean there is no questions
A)
145 - 5d
5d = 145, set equal
29 days to lay all the track
b)
5*19 = 95
145-95 = 50
After 19 days, they have 50 miles to go.
So the distance formula: d = rad (x2 - x1)^2 + (y2 - y1)^2
it doesn't matter what order you do, you just have to make sure it's a y coordinate for y and an x coordinate for x.
rad (9-5)^2 + ((-6)-1)^2
rad 4^2 + (-7)^2
rad 16 + 49
rad 65
