2x = Twice your age
200 = Two hundred less
> -1 = more than negative
With the information given, your equation would be:
200-2x>-1
If 4 are $2.00 , then x3 to get 12 light bulbs and 2x3=6 so it's $6.00
B. 60 m is the height of the triangle
Answer: a) 
Step-by-step explanation:
Since we have given that

a.) Find the inverse of f(x) and name it g(x).
Let f(x) = y
So, it becomes
Switching x to y , we get


b) . Use composition to show that f(x) and g(x) are inverses of each other.

Similarly,

so, both are inverses of each other.
c) Draw the graphs of f(x) and g(x) on the same coordinate plane.
As shown below in the graph , Since for inverse function we need an axis of symmetry i.e. y=x
And both f(x) and g(x) are symmetry to y=x.
∴ f(x) and g(x) are inverses of each other.
