⦁the equation (x + 5) + (y + 3) = 169 models the position and range of the source of a radio signal. describe the position of the source and the range of the signals.

Step-by-step explanation:

The problem tell us that the position and range of the source of a radio signal is described by the next equation:

Let's isolate y and represent the previous equation the slope-intercept form:

Now, we can say that the range of the signal as a function of the position is given by:

Where:

Analyzing the function we can conclude the next things:

from the figure we get,

the x axis shows   the months and,

the y-axis shows the number of satisfied customer.

each line or each cell in upward direction (y-axis) shows 500.

the appropriate scale for the y - axis is: -

a = 2000 customers

b = 4000 customers

c = 6000 customers

d = 8000 customers

e = 10000 customers

f = 12000 customers

g = 14000 customers

i think it is c hope that
