fan and medal which number is the solution to the inequality 8

OpenStudy (anonymous):

If we plug in 2 we will get 2(7-2)>8 2(5)>8 10>8

OpenStudy (anonymous):

If we plug in 8 we get 8(7-8)>8 8(-1)>8 -8>8

OpenStudy (anonymous):

thank you

OpenStudy (anonymous):

If we plug in -1 we get -1(7-(-1)).8 -1(8)>8 -8>8

OpenStudy (anonymous):

If we plug in 0 we get 0(7-0)>8 0>8

OpenStudy (anonymous):

so you can solve from there

OpenStudy (anonymous):

It is A

OpenStudy (anonymous):

so here,

OpenStudy (anonymous):

A. 2 x(7 – x) > 8 7x - x^2 > 8 x^2 - 7x +8 < 0 x = (7 +/-V17) / 2 -> x = 5.56, 1.43 => Since the solution range ( 1.43, 5.56) which satisfies x = 2
