g(x) = 2x-6
f(x) = -4x +7
(g•f)(x) = g(f(x))
= 2(f(x)) - 6
= 2 ( -4x+7) -6
= -8x + 14 -6
= -8x +8
now
(g•f)(1) = -8(1) + 8= -8+8
= 0
so option a is answer
Tan80=5.67
2tan70+tan10=5.67
So tan80=2tan70+tan10
Hey There!
In order to simplify this expression, you would have to combine the like terms.
9+1 = 10
Nothing else could be done, therefore the answer would be.
7v + 10
Hope this helped!
