Let the width of the room be = x
Length of the room = 3x, Since it is three times as wide
Perimeter = 80m
Perimeter = 2*(L + W) = 2*(3x + x) = 80
2*(3x + x) = 80
2*(4x) = 80
8x = 80 Divide both sides by 8
x = 80/8
x = 10, But length = 3x, = 3*10 = 30
Length = 30m

So this equation is in exponential equation format, which is 
, with a = initial value (aka y-intercept) and b = growth/decay.
Looking at our equation, since 1 is in the a placeholder, this means that the <em>y-intercept is (0,1)</em>. Looking at our four graphs, the only graph that has (0,1) as the y-intercept is the third graph. Therefore, <u>the correct answer is the third graph.</u>

Step-by-step explanation:
Answer:
-1
Step-by-step explanation:
For piecewise functions, you should look at the range of values and see where the number you are looking for falls. In this case, -1 is included in the domain of the middle equation, so you will be using f(x) = x
Then, all you have to do is plug in -1 for x, so f(-1) = -1
