given the function R(x)= x+5/x-5 find the value of x that make the function greater then or equal to zero. write the solution in interval notation

Step-by-step explanation:

Hello,

First of all, let s take x real number different from 5, as we cannot divide by 0

So the solution is

Thanks

step-by-step explanation:

no, her answer is not correct.   we square the lengths of all sides and then determine whether the pythagorean theorem holds here:

9² + 15² = 306.   this is not equal to the square of the longest side ( that square being 395.   answer c is correct.
