Answer:
C
Step-by-step explanation:
The graph in this case represents exponential decline.
A) the length on the top is 2ft. You were supposed to subtract 11ft from 9ft. The length on the bottom is 17. You get that by adding 5ft and 12ft
b) then you add up all the lengths together.
2+5+12+11+9+17= 56ft
That's 20% of 305.
You could set up the problem as a ratio.
20 x
--- = ------
100 305
100x = 6100
x = 61
Answer:
f(x)=2x-1
Step-by-step explanation:
The output is f(x). The input is x.
The prompt says to multiply the input by 2, so 2x.
Then subtract 1 to get f(x).
