<u>Part 1: Finding radius</u>
The radius of a circle is defined as the distance from the center to a point on the circle's circumference.
Using the distance formula,
<u>Part 2: Finding the point with x-coordinate -15</u>
Let the y coordinate of the point be y. Then, we have the point (-15, y). Substituting into the distance formula,
First, you wrote -3x-7<20, that means -3x<20+7
or -3x<27 and we have x>-9
We draw the line of equation x= -9 and we have the set of solution is the haft of the plan on the right of the line x= -9
