Answer to the first question
-5x + 3x > 22
-2x > 22
x < 22/-2 (greater than sign changes to less than sign when you divide with negative number)
x < -11
Answer: radius of the largest circle is Zero.
Step-by-step explanation: A circle can't fit into an ellipse with such coordinate (3,0). What that coordinate means is that the ellipse lies along the x axis 3unit from the origin along the x axis and 0 unit from the origin along the y axis. At which no circle can fit in.
Moreso, the the coordinates at which the circle intercepts the ellipse as to be uniform not (3,0).
A circle as a constant radii coordinate on both axis.
I believe you can now see why my answer is Zero.
