So, these are actually pretty simple once you learn the equality used to solve for "x" and when to implement this method. You can use this equality to solve for a segment "x" anytime that two secant lines cutting through a circle come from the same point outside the circle.
Secant: by geometric definition is just a straight line that cuts a curve into multiple pieces.
I did one of them for you hopefully you can use my work for "a" to help you solve for "b". For a. I got x=7.

ANSWER
EXPLANATION
First we need to find the equation of the boundary line which passes through (-1,-3) with a y-intercept of -5.
The slope of this line is
The equation of this line is
Since the boundary line is solid and the upper half plane is shaded the required inequality is
