Eliminating parentheses gives
10.5u -18 = 8.25
10.5u = 26.25
u = 2.5
The value of u is 2.5.

Answer by JKismyhusbandbae: So this is really simple. You are probably making this out harder than it needs to be. Consider the set of ordered pairs {(-1,0), (4,-5), (6,-6), (9,11), (10,14)}. This set of ordered pairs is a function because for each value of x there is one and only one y-value. This means that the x value never repeats. Therefore any function is a function when the x value never repeats.
Looking at the table we want to find all it's ordered pairs: (0,4), (1,2), (2,3), (3,9), (4,1).
F(2) is 3 so when x equals 2.
So the ordered pair is (2,3) 2 is the x value and the f(2) is 3.
Look it up I will find it

Answer:
-10
Step-by-step explanation:
We can figure out that the number line is by four.
How?
There is one line between 10 and 2. Sooo:
10 - 2 = 8
8 / 2 = 4
If we check it (10 - 4 - 4 = 2) it checks out!
Using this information we can figure out what the blue dot is.
2 (given) - 4 (incriments of number line) - 4 - 4 = - 10
There is our answer, -10!
