Answer:

OK, lets start by drawing a basic graph (the first one) so we can visualize.
We already know that the y coordinate of the circle's center is
.
We know that the circle is tangent to the
axis at 
That means the x coordinate of the center has to be
, as the tangent is a point on the edge of the circle that touches a line at exactly one point.
The radius is the distance from the center of the circle to its edge. We know the center's location now, it is
and a point on the edge of the circle (the tangent point) which is
. so the distance between the points is 4 which is the radius (you can use the distance formula, but it's quite oblivious.)
We can imagine the circle should look like this (the second one):
Now we can piece together an equation
The equation of a circle is
where
is the center and
is the radius. When we put the numbers in: we get
which can be simplified into
which is the answer.

Answer:
The cost for each pound of trail mix is $ 1.75 and each pound of jelly beans is $ 2.75.
Step-by-step explanation:
Let each pound of trail mix cost
dollars and each pound of jelly beans cost
dollars.
Given:
7 pounds of trail mix and 9 pounds of jelly beans cost $ 37.
So,
--------------- 1
Also, 5 pounds of trail mix and 3 pounds of jelly beans cost $ 17.
So,
--------------- 2
Multiplying equation 2 by -3, we get

Now, adding equations 1 and 3, we get

Now, plug in
in equation 1 and solve for
.

Therefore, the cost for each pound of trail mix is $ 1.75 and each pound of jelly beans is $ 2.75.
