.45x+.55x=200
Combine like terms
1x=200
So x is 100
Or you can do 45%+55%=100%
And 100% of 200 is 200
Given:
The function is:

To find:

and the graphs of these functions are shown below.
Answer:
<em>K</em>=<em>2h</em>
<em>k</em><em>=</em><em>0.5h</em>
<em>k</em><em>=</em><em>h</em><em> </em><em>+</em><em> </em><em>1</em>
<em>k</em><em>=</em><em> </em><em>0.5h</em><em> </em><em>+</em><em> </em><em>1</em><em>0</em>
