True because 5(3)=15-1=14 and 14/2=7
The Slope of this problem = 7/3
Since f(2) is not given in the function definition, you must use f(n) with n=2. That tells you
... f(2) = -29 -f(1)
Now, f(1) is defined, so use that value.
... f(2) = -29 -(-16) = -29 +16
... f(2) = -13
X - shorter piece
3x - 2 - longer piece
x + 3x -2 = 18
x + 3x = 18 +2
4x = 20 | : 4
x=5
3*5 -2 = 15 - 2 = 13
shorter piece: 5 ft
longer piece : 13 ft
I hope this helps
For example: A) 5+(-4)+12.65.
5+ (-4)= 1
1+12.65= 13.65
thats what it means by show how you know it right. In other words show your work
