<p>PG 327: #17</p>
<p>If y = 1 + (1/x) and x > 1, then y could equal:</p>
<p>A. 1/7
b. 5/7
c. 9/7
d. 15/7
e. 19/7</p>
<p>x can only equal 7, right? In which case it'd produce an answer of 8/7 which is not listed...</p>
<p>y is any decimal number greater than 1 and less than 2. C is a valid response</p>
<p>But what would x be in that case to produce 9/7?</p>
<p>Ooh. Nevermind. I see.</p>
<p>wrong x could be any values X>1 not just integers, it could be fractions too. </p>
<p>If you still don't believe it, try plugging in all the choices for y, and solve for x to see that c is the only answer that produces X>1</p>
<p>I know. I know. I understand. </p>
<p>That sucks. I hate these problems. I'd think of only integers, and I'd probably miss it. I'd never be able to reason it through by thinking it has to be larger than 1, and smaller than 2.</p>
<p>Wow, that's cool! I was doing that today too hahaha. Test 3 or 4 right?</p>
<p>this is what we do for fun...................</p>
<p>c is the only answer and you don't even have to think....1+some number less than 1 will always be between 1 and 2</p>
