Oh no face palm not again.... I have to break my promise which is "not to respond to this again" (for the sake of posterity). benji93 please go back to my responses and read them very well. It is not about the solution to the problem (Mathematica can provide me with solution to inequations in 3 seconds). naturalwaves (by the way I like the bloke for his immense contribution to this forum) gave a handwritten solution to the inequation... derived a quadratic inequality from it and solved it but made a slight mistake which i pointed out to.... but in retrospect it seems he apparently misconstrued my solution to his quadratic inequality for the solution of the original inequation which I thought he was purposely intellectually trolling me because I made it clear it was for his derived quadratic (that is why i kept trying his solution to his quadratic inequality to see if it satisfies it rather than the inequation and also he was trying to extend the solution of his quadratic to the original inequation).

I really hope this will be my last response to this. Cheers!

Soln
2+3=5
:.
2*5=10
3*5=15
60/15=4
60/10=6
Then
6/4=1.5h
1_ 1/2h

that not the answer the answer is 1.2 hours

Am new here.i study metallurgical engineering at yaba tech My name is bello yunus my questiin goes like this paul paint a fence for 2 hours and fred paint the same fence for3 hours what time will it take both of them to paint the fence together

naturalwaves:

Thanks for the compliment. Yeah, most of your points were on the quadratic till you mentioned at a time that the values will fail for both the quadratics and the parent equation. Moreover, the quadratic was derived from the equation but you kept on hiding behind the "if the qaudratic is correct tag". What you should have done is to check if the derived quadratic is wrong and correct the derived quadratic if it is wrong or even provide another solution to the problem from the beginning so that we can all follow through. I believe that would cost you nothing except if you do not have a pen all the while or you were not just in the mood to solve anything. It is a good thing to have someone scrutinize things so that everyone can get the best. It was never a game of right or wrong or ego play like you thought.

Richiez:
Good to see that this thread is still active... with fresh gurus trooping in...
There are plans to organize a math quiz next month.

Patbaker:



Yeah
i just hope we re all given the admission since the course is not competitive

captainbangz:
A point P moves so that it is equidistant from two points Q and R. Given that PR=8 and that <PRQ=30'. Compute the length of the line segment QR.

aceman88:
help

aceman88:
No help in view for the questions?

Mechanics96:


I assumed that you meant <PRQ=30° which is most likely (as 30'=0.5°)

|QR|=8√3 units =13.856 units

Iamcyborg:
Pls someone should help me solve this; find the two values of y which satisfy the simultaneous equation 3x+y equals 8, x squared +x-y equals 6.

Mechanics96:
@ Aceman, me I just dey enter oo, sori it's late

Iamcyborg:
thanks....but it's find d two values of y and not x. The options are: 1&5, 2&5, 0&5, -1&5

aceman88:




Thanks so much my guy. the exam was written today. Your effort really helped a lot.
