Question #217361

The solutions to the inequality ( [(x1/2)(x-5)] / lx-7l )>0 are all the x elements of R such that?


A. x>0 and x


Expert's answer

x1/2(x−5)∣x−7∣>0\dfrac{x^{1/2}(x-5)}{|x-7|}>0

x1/2:x≥0x^{1/2}: x\geq0

∣x−7∣≠0=>x≠7|x-7|\not=0=>x\not=7

Then


x−5>0,x≠0,x≠7x-5>0, x\not=0, x\not=7

The solution is


x∈(5,7)∪(7,∞)x\in(5, 7)\cup(7, \infin)

The statement that the solutions to the inequality x1/2(x−5)∣x−7∣>0\dfrac{x^{1/2}(x-5)}{|x-7|}>0 are all the xx elements of R\R  is False.
