The answer is the second option, or Ray BE is a bisector of angle ABE.
Answer:
54 and 30
Step-by-step explanation:
84÷2=42-12=30
42+12=54
Answer:
1/2, 11/6
Step-by-step explanation:
y=-4+9y
9y-y=4
8y=4
y=1/2
3x-5=1/2
3x=5+1/2=11/2
x=11/6
Answer:

Step-by-step explanation:
First find the slope using the slope using the given points. Remember that the slope is the change in y over the change in x.

So now we have the equation
, and we need to find out what b is. We can do this by pointing a point (either one, but I'll use -1,2) into the equation

Rearrange the equation so it equals b

Put it together and that's the final equation!

Answer:
n=-1
Step-by-step explanation:
distribute the 7 to n+4 to get 7n + 28 = 21. subtract 28 from both sides to get 7n = -7. divide both sides by 7 to get n=-1
you could also divide everything by 7 at the beginning to get n+4=3, then subtract 4 from both sides to get n=-1
