<h3>
How to identify the source and range of the signal?</h3>
Remember that a circle of radius R, centered at the point (a, b) is described by the equation:

In this case, we have the equation:

First, notice that 49 = 7², so we can rewrite:

Then, comparing this with the general circle equation, we can see that the center is at (5, -2) and the radius is R = 7.
Then the source is at (5, -2) and the range is 7 units.

First you do the parentheses wich is (3 + 1 ) and that equals 4 and now you do 6 times 1 and that eqal 6 and then you multiply 6 by 4 and the answer is 24
<span>For each one . . .
=> solve the
equation for 'y'. That means massage it around until it's
in the form
of <em> y</em> = (thing1) <em>x</em> + (thing2).
=> When you do that, then 'thing1'
is the slope of the line on the graph,
and 'thing2' is the number
where the line crosses the y-axis.
=> When you have those two
numbers, drawing the line on the graph
is a piece-o-cake.</span>
