sqrt((x-5)^2) = 5-x? sqrt((x-5)^2) = |x-5| |x-5| = 5-x The above equation has two values x-5 = 5-x or -(x-5) = 5-x depending on whether (x-5) > or < 0 1. -x|x| > 0 the above is possible only for x < 0, therefore (x-5) < 0 So |x-5| = 5-x => -(x-5) = 5-x. SUFF 2. States that (x-5) < 0 SUFF IMO D I th...

I think C is the correct answer. If the rate of assemblance had increased that could be one factor contributing to the decline of assemblers since lesser people will be required to assemble the television, provided the number of televisions required remains the same. Since this provides an alternate...

Only B points out the flaw. Since the comparison for the argument is done between federal expenses in Arcadia and profits earned from factories in Arcadia, the argument assumes that it was the industrialists funding the war and hence they made no profit. If the expenses were incurred by people other...

We are using it to "Negate" a theory. It is to be presented as an argument "Against". It can only be used to refute B, hence B should be the answer.

The argument says that after a study of other contributing factors towards accidents, insurance companies will come up with better guidelines for safer travel and hence prevent future accidents. So the argument is presuming the investigation of current accidents will ...

If x, y, and k are positive integers such that (x/(x+y))(10)+(y/(x+y))(20)=k and if x<y, which of the following could be the value of k? a.10 b.12 c.15 d.18 e.30 PS: i didnt understand the long explanation for the correct answer D (x/(x + y))(10) + (y/(x + y))(20) = k and x < y 10x + 20y = k(x + y)...

Continuing from the discussions above........ Here is my solution... Distance = d = same for both trips.. Magic Formula: Distance = Time x Speed Lets find the time for each. Uphill = d/x Downhill = d/y Total Distance = 2d Total TIme = (d/x + d/y) So average Speed = (2d)/(d/x + d/y) = (2xy)/(x+y) Hen...
