Answer:

Step-by-step explanation:

This is a neat question. I suggest that you graph it on desmos. You will lean a bunch by doing it. These are the graphs you should put on there.
y = 1/(abs(x - a) - 1):In red
When you use your down arrow, a new entry will be given you. You can use your mouse to operate the slider you get when you type a = 5
so your next graph should be a = 5
Use your down arrow again. Put in x = 4: Blue Line
Use your down arrow again. Put in x = 6: Green Line

Be patient with this. Play with the sliders to see what they do. I believe you are correct, but I am not certain of the second union although it does look correct.

The graph I have enclosed is of what I have described in the steps above. Make sure you try it all out.

Answer:

x = 41.67

Step-by-step explanation:

The above equation, would be simplified or divided into parts;

Therefore, the given equation becomes;

A/x = B/C

Where;

A = (15.2*0.25-48.51/14.7)

B = (13/44-2/11-5/66/2.50)1.2

C = 3.2+0.8(5.5-3.25)

x = unknown variable.

Part A

(15.2*0.25-48.51/14.7) = (15.2*0.25 - 3.3)

A = (3.8 - 3.3)

A = 0.5

Part B

(13/44-2/11-5/66/2.50)1.2 = (0.3 - 0.18 - 0.030) * 1.2

B = 0.09 * 1.2

B = 0.108

Part C

(3.2+0.8(5.5-3.25)

C = 4*(2.25)

C = 9

Substituting the values into the equation, we have;

0.5/x = 0.108/9

Cross-multiplying, we have;

9 * 0.5 = 0.108x

4.5 = 0.108x

x = 4.5/0.108

x = 41.67

Answer:

We can rewrite this as $\frac{200x}{x} + \frac{-300}{x}$ .

$\frac{200x}{x}$ simplifies to 200 after eliminating x from the numerator and denominator and $\frac{-300}{x}$ becomes $-\frac{300}{x}$ so the final answer is $200 - \frac{300}{x}$ .
