Step-by-step explanation:
10 feet = 1 inch
50 feet = 5 inches
Do the same thing for the length.
If you don't under stand.
50/10 = 5
1/10 = x/50
10x = 50
x = 50/10
x = 5 inches
Then you do the same with the lenght.
This is an arithmetic sequence because we are adding the same amount each time. In this case, we are adding -4 to each term to get the next term
17 + (-4) = 13
13 + (-4) = 9
9 + (-4) = 5
and so on. The starting term is
The common difference is
The nth term of the arithmetic sequence can be found by this formula
For instance, if n = 2, then,
which matches up with the second term listed.

Answer:
y = -3x -4
Step-by-step explanation:
A perpendicular line has a slope that is the negative reciprocal of that of the given line. When the equation starts out in standard form, a line with negative reciprocal slope can be written by swapping the x- and y-coefficients and negating one of them.
The given x- and y-coefficients have the ratio 1:-3, so we can use the coefficients 3 and 1 for our purpose.
The usual process of making the line go through a given point can be used. That is, we can translate the line from the origin to the desired point by subtracting the point coordinates from x and y. Then we have ...
3(x+3) +(y-5) = 0

This is "an" equation. It is in no particularly recognizable form. It can be rearranged to the form y = mx + b:
3x +9 +y -5 = 0 . . . . . eliminate parentheses
y = -3x -4 . . . . . subtract terms that are not "y"
