Answer:
15
Step-by-step explanation:
As you can see on the side it says 15 and that is the length of the structure and it would be the same all around
6x+8x+40=180
14x = 140
x = 10
7y + 3y - 10 = 180
10y = 190
y = 19
This is a nice twist to see if you can read the graph and interpret what it means.
f(1) is the y value of the graph when x = 1
So start at x = 1 and find the y value. Go straight up. The point you reach is (1,3)
so g(1) = 2*f(1) - 1
g(1) = 2*3 - 1
g(1) = 5
Answer
g(1) = 5
The answer correct answer is b
