Answer:
Step-by-step explanation:
In this case we know the composition of f and g is

Thus if we change x by 3 we get

You would want to add all of the angles together to find the sum. Set this equal to 360.
2x-9 + 2x-9 + x + x + x = 360
Combine like terms,
7x-18 = 360
Add 18 to both sides,
7x = 378
Divvied both sides by 7,
x = 54
Answer: D
Explanation: Apply the pythagorean theorem (a^2 + b^2 = c^2) to get 11^2 + b^2 = 18^2. From that you can solve for b and you get the square root of 203.
Hope this helped! :)
Answer:
X = 1
Step-by-step explanation:
When x = 1, gx is equal to 3 in both graphs. The input of x = 1 produces the same output value for both functions.
