Answer:
<u>Algebraically</u>
0.5x-7= √(-5x+29)
(0.5x-7)² = -5x+29
(0.5x)² - 2*0.5x*7 + 7² = -5x+29
0.25x² - 7x + 49 + 5x - 29 = 0
0.25x² - 2x + 20 = 0
Its discriminant is:
b² - 4*a*c
(-2)² - 4*0.25*20
-16 < 0
Therefore, the equation has no solutions.
<u>Graphically</u>
In the picture attached, the plots of the functions are shown. We can see that they don't intersect each other, and that is why there is no solution.
Jeffrey has 1529 stickers remaining
<h3>Further Explanation</h3>From the problem above we know that
Jeffery bought 203 sheet of stickers
Each sticker has a dozen stickers or equal to 12 pcs stickers
He gave away 907 stickers
How many stickers does Jeffery have now?
<u>Step by step explanation</u>
First, we need to calculate the total stickers that Jeffery has, we are going to use the area model methods (see the attachment)
Total stickers that Jeffery has is 2436 pcs of stickers, he gave away 907. Total remaining stickers is
or
2436
<u> 907 -</u>
1529
Now, Jeffery has 1529 pcs of stickers.
