Answer:
I believe you, Divide x x by 1 1 .
Step-by-step explanation:
Since g(h(x))=x g ( h ( x ) ) = x , h−1(x)=2x5−85 h - 1 ( x ) = 2 x 5 - 8 5 is the inverse of h(x)=52x+4 h ( x ) = 5 2 x + 4 .
sorry if im wrong
Good job oh my God you are so smart oh my God a good job bro
Answer
Sol: The correct answer is b. three planes that contain point B are ABD, AEF and DHF.
we are given
x^2-4x-5
we can use formula
x^2-(a+b)x+ab=(x-a)(x-b)
so, we have
a+b=4
ab=-5
now, we can solve for a and b
and we get
a=5, b=-1
now, we can plug it in formula
x^2-4x-5=(x-5)(x+1) ............Answer
