Answer:
Which Question?
Step-by-step explanation:
Domain is X and Range is Y
The final answer would be:
9x / (x-8)
The exact steps are shown in the attached picture.
Note that when dividing two fractions, we convert the division into multiplication and flip the second term.
Answer:
<em>x = 0.05</em>
<em>x = 1.57</em>
Step-by-step explanation:
The given equation is:
![e^x-\ln 2x = 3.7](https://tex.z-dn.net/?f=e%5Ex-%5Cln%202x%20%3D%203.7)
Moving all terms to the left side:
![e^x-\ln 2x - 3.7=0](https://tex.z-dn.net/?f=e%5Ex-%5Cln%202x%20-%203.7%3D0)
Now we define a function:
![y=f(x)=e^x-\ln 2x - 3.7](https://tex.z-dn.net/?f=y%3Df%28x%29%3De%5Ex-%5Cln%202x%20-%203.7)
The solutions of the equation are the values of x such that y=0.
Since the function cannot be solved by algebraic methods, we use a graphing tool.
Those points where the graph crosses the x-axis are solutions of the equation.
Please refer to the graph in the figure below.
We can clearly identify there are two solutions at
x = 0.05
x = 1.57
20; make both equations equal so whatever you plug in for x will be the same
2(4x+10)=8x+k
8x+20=8x+k
k=20
