\[\int\limits_{7}^{8}f(x)=-8 \] I think..

Thank you i entred it and your answer was correct!
anonymous
  • anonymous
how did you get this?
Luigi0210
  • Luigi0210
Well I used the given information and graphed it out I graphed each integral individually
Luigi0210
  • Luigi0210
And they gave the over value from 6-9 which is 6 So I added up both integral values: 14-x=6

I see. what about the second one?
Luigi0210
  • Luigi0210
It would be the opposite.. since it's going backwards whenever the integral has a lower limit that is higher than the upper limit it'll be negative \[\int\limits_{8}^{7}f(x)dx=-\int\limits_{7}^{8}f(x)dx\]
Luigi0210
  • Luigi0210
So it's -(-8)=8
Luigi0210
  • Luigi0210
Does that make some sense? :l

  • anonymous
the second one is wrong when I entred it
Luigi0210
  • Luigi0210
Woops, I did not see that 6..
Luigi0210
  • Luigi0210
\[-\int\limits_{7}^{8} 6(-8)-6\] so it's 54 if I'm not mistaken again :/

  • anonymous
correct! you are supre. could you explain?
Luigi0210
  • Luigi0210
How I obtained the answer?
anonymous
  • anonymous
yes,
Luigi0210
  • Luigi0210
Well since we know that: \[\int\limits_{7}^{8}f(x)dx=8\] We can switch the integrals around and we already solved for \[\int\limits_{7}^{8}f(x)dx \] we just plug in 8 for \[-\int\limits_{7}^{8}6f(x)-6\]
Luigi0210
  • Luigi0210
so it'll be -[6(-8)-6] -[-48-6] -[-54] 54
Luigi0210
  • Luigi0210
sorry i meant -8 on the first integral
