- Now, we know cos(60°) =
. So put the value there.

Hence LHS = RHS [Proved]
Hope you could understand.
If you have any query, feel free to ask.
F( g(x) ) = 10( [x-6] ) + 6 = 10x - 60 + 6 = 10x - 56
Please do the other problem in a similar fashion. For "x" in g(x), substitute "10x+6."
Answer:
Step-by-step explanation:
F(x)=-x+5
So
f(-4)= -(-4)+5
f(-4)= 4+5
f(-4)= 8
Only we have to substitute value of x then after simplification we will get answer..Hope this will help
