Answer:
f(x+2)=3x+10
Explanation:
f(x+2) means replace all the xs with (x+2)
f(x)=3x+4
f(x+2)=3(x+2)+4
Now simplify
f(x+2)=3x+6+4
f(x+2)=3x+10
Answer:
$6.50
Step-by-step explanation:
39 / 6 = 6.5
If BC bisects BED, this means that BED is split into two equal parts and that CED = BEC. We can see that AD forms a straight line, which means BED and AEB must be supplementary, ow have a sum of 180 degrees. Since CED has the same angle measure as BEC, this means that BED can be found by multiplying as shown:
Now find the value of x:
Combine like terms: 
--> 
---> 
Isolate x --> 
x = 10
Plug in the value of x:
--> 
---> 
----> 
So AEC is 139 degrees.

Slope intercept form equation:
y=mx+C
----------------------
We already know that m=-4. Now, let's find the value of C.
--------------------
m=-4, and when x=-1, y=5.
(5)=(-4)*(-1)+C
5=4+C
5-4=4+C-4
1=C
-----------------
Therefore the slope intercept form of the function is:
y=-4x+1
