Best ResponseYou've already chosen the best response.1\[\int\limits_{7}^{8}f(x)=8 \] I think..

Best ResponseYou've already chosen the best response.1Well I used the given information and graphed it out I graphed each integral individually

Best ResponseYou've already chosen the best response.1And they gave the over value from 69 which is 6 So I added up both integral values: 14x=6

Best ResponseYou've already chosen the best response.0I see. what about the second one?

Best ResponseYou've already chosen the best response.1It 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 \[\int\limits_{8}^{7}f(x)dx=\int\limits_{7}^{8}f(x)dx\]

Best ResponseYou've already chosen the best response.1\[\int\limits_{7}^{8} 6(8)6\] so it's 54 if I'm not mistaken again :/

Best ResponseYou've already chosen the best response.1How I obtained the answer?

Best ResponseYou've already chosen the best response.1Well 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 \[\int\limits_{7}^{8}6f(x)6\]

Best ResponseYou've already chosen the best response.1so it'll be [6(8)6] [486] [54] 54
