All you have to do is move the denominator on the other side, by multiplying.
a-10
------- = -9
20
multiply 20 x -9
= -180
then it becomes a-10=-180
+10 +10
a=-170
Ok so any number tat makes the denomenator 0 or makes the inside of a square root negative is restricted
we only have a denomenaor so
100v=0
v=0
therefor 0 is the excluded value since 0/0 doesn't make sense
Answer:
A. {-9, -4, -1}
Step-by-step explanation:
Every number on the f(x) side is the domain which is the input numbers.

Answer:
x = 5.2
Step-by-step explanation:
See the diagram first.
We know that in a triangle if we draw a line parallel to the baseline then it will divide the other two lines of the triangle in the same ratio.
Therefore, from the given figure it is clear that 
⇒ 3x = 26 - 2x
⇒ 5x = 26
⇒ x = 5.2 (Answer)
