For this case we have the following functions:
We must find
By definition we have to:
So:
We must evaluate the composite function for 
ANswer:
Your answer would be 17/3
Use KMF (Keep multiply flip)
keep the first fraction as it is
change sign to multiplication
flip numerator and denominator of last fraction
then finish
<h3>Simplifying
</h3>
5.5 + -1x = -4.5 + -1x
<h3>
Add 'x' to each side of the equation.
</h3>
5.5 + -1x + x = -4.5 + -1x + x
<h3>
Combine like terms: </h3>
-1x + x = 0
5.5 + 0 = -4.5 + -1x + x
5.5 = -4.5 + -1x + x
<h3>
Combine like terms:</h3>
-1x + x = 0
5.5 = -4.5 + 0
5.5 = -4.5
<h3>
Solving:
</h3>
5.5 = -4.5
<h3>
This equation is invalid, the left and right sides are not equal, therefore there is no solution.</h3><h3 />
Hope this helps!
If you use your subtraction right when you use deceleration as for example like 4.5 from 79 well you know it had to slow down so the correct Answer for this would end up as 17 .5 Try the easy way like
79 dived by 4.5 would get you the same answer but don't divide backwards you will get an in correct answer
hope i helped;)
