Answer:

x - 4 = 0

Step-by-step explanation:

Slope is undefined

So, slope m = 1/0

Line is passing through the point (4, 8)

Equation of line:

$y - y_{1} = m(x - x_{1} ) \\ \\ (y - 8 )= \frac{1}{0} (x - 4) \\ \\ (y - 8 ) \times 0= (x - 4) \\ \\ 0 = x - 4 \\ \\ x - 4 = 0 \: \\ is \: the \: required \: equation \: \\ line.$

Answer:

729

Step-by-step explanation:

3 to the power of 2 means 3 * 3 which is 9. 3 to the power of 4 means 3 * 3 * 3 * 3 which is 81. Finally, 9 * 81 which gives you 729.

Answer: $x = \frac{mn(q - p)}{n-m}\\\\$

================================================

Work Shown:

Part 1

$\frac{x-m}{m} + p = \frac{x-n}{n} + q\\\\\frac{x-m}{m} - \frac{x-n}{n} = q - p\\\\\frac{n(x-m)}{mn} - \frac{m(x-n)}{mn} = q - p\\\\\frac{xn-mn}{mn} - \frac{xm-mn}{mn} = q - p\\\\\frac{xn-mn-(xm-mn)}{mn} = q - p\\\\$

Part 2

$\frac{xn-mn-xm+mn}{mn} = q - p\\\\\frac{xn-xm}{mn} = q - p\\\\\frac{x(n-m)}{mn} = q - p\\\\x(n-m) = mn(q - p)\\\\x = \frac{mn(q - p)}{n-m} \\\\$

-------------------------------

Explanations:

There are quite a bit of steps. I decided to break things into two parts.
The goal is to get x all by itself on its own side, which is why I subtracted (x-n)/n from both sides in part 1, step 2. I also subtracted p from both sides.
Afterward, I gave each fraction the LCD mn. I multiplied top and bottom of the first fraction by n/n. I did a similar operation to the second fraction, but with m instead.
From there, we distribute and simplify. The mn terms cancel on the left side numerator (second step of part 2).
The n≠m is there to prevent the denominator (n-m) from being zero. We cannot divide by zero.
