<p>How do you solve this question with certainty? I tried estimating but couldn't choose bwteen D and E.
Thanks!</p>
<p>Which question? There are 3. And they’re very hard to read. The picture is quite small on my computer.</p>
<p>Number 11! sorry about that</p>
<p>Coordinate S is (1.5, 4), therefore the center of the circle is (1.5, 0)</p>
<p>The distance between S, and the center of the circle is 4. (Distance formula).</p>
<p>Now the X coordinate is required from point R, which is all we can provide anyway. Since S, and the center is a radius and its length is equal to 4, therefore the distance between the center of the circle and R must also equal 4.</p>
<p>-2.5 -> 1.5 = 4</p>
<p>Your answer is E, -2.5</p>
<p>I can’t even read the problem.</p>
