The issue with using the side-splitter to solve for x is that the side-splitter theorem is used to find lengths of the sides being split by parallel lines. In this case, the x is on a line that is parallel and thus could not be solved for using this theorem. 

If we created a triangle where the tops of the non-parallel lines connected, we would be able to compare the following and solve:

\frac{M1}{M2} =  \frac{N1}{N2}

However, none of this would help us solve for x using this theorem.

It is reported in USA Today that the average flight cost nationwide is $445.99. You have never paid close to that amount and you
nlexa [21]

Answer:

H_0 : \mu \leq 445.99

H_a : \mu > 445.99

Step-by-step explanation:

It is given the average cost of the flight nationwide is $ 445.99

I wanted to \text{perform the hypothesis test} to determine that the true average is greater than $ 445.99

Let the hypothesis that the true average is actually greater than $445.99

Therefore,

the \text{null hypothesis} for the test is :

H_0 : \mu \leq 445.99

And the alternate hypothesis is :

H_a : \mu > 445.99

What is the answer please?
Marina CMI [18]

Answer:

The one you are on, f(x+2)+4

Step-by-step explanation:

First, we can see by the 0 point that it is just moved up by 4 and not left or right any, so we want to see how it has changed without the +4.  


in g(x) the x changes by two, 0 to 2, and the y changes by one, 4 to 5.


Hopefully you can tell what the function being manipulated is.  It is x^3  so if we write that instead of f(x) in the answers the first one for instance would be (x/3)^3-4.  (let me know if that doesn't make sense)


SInce we already know it's being moved up by 4, we know it's one of those with +4 at the end.  It's easy enough to guess and check, but the process to find the answer is pretty easy.  We also know that at 2, the change is 1.  So without the +4 at the end, what would let us change 8 to 1?  dividing it by 8, which is also 2^3.  so that means (2/2)^3.  So the answer is we want f(x/2) witht he +4 at the end.  


Hopefully that made sense, I'd be happy to explain further if you need though
