Answer:Let the number be x, then (x - 9)^2 = x - 3
x^2 - 18x + 81 = x - 3
x^2 - 19x + 84 = 0
(x - 12)(x - 7) = 0
x = 12 or 7

Answer:
<em>The slope would be</em><u><em> -1/2.
</em></u>
Step-by-step explanation:
Since, the midpoint of the segment joining the points P (0, -4) and B (8, 0),
<em>
= </em><u><em>( 4, -2 ),
</em></u>
Now, the slope of the line passes through the origin and the point ( 4, -2) is,
= <u>-1/2</u>
