ps. i took a screen cap, because i dont even know how to key in those symbols
pss. i HATE math =(
I just began class today.. I have no experience with any of this and the course work does not begin to explain it.. i googled the symbol "|" it tells me that it means "divided into" that tells my feeble mind that x/x=1; and so "1 is equal to or less than -4.25" obviously false... the solution gives me -infinity..... my brain hurts.... what do?
so the actual charge is irrelevant to the solution?
just that the value of x is less than or equal to the difference to zero(+/-) of the value of the given?
so the answer set (-infinity,4.25) -Plato; is a ray from point (4.25,0) towards negative, infinitely along the x axis?
No, the absolute value is a DISTANCE. You can only ever have a POSITIVE value for a distance (so it turns all numbers positive). Therefore |-17/4| = 17/4, and the set x <= |-17/4| is the same as x <= 17/4. So in interval notation your answer is (-infinity, 17/4].
