Answer:

x = 2 (For First question)

Step-by-step explanation:

8^ 1/6 * 2^x = 32^1/2

8^1/6 * 2^x 8^1/6 = 32^1/2/8^1/6

2^x = 32^1/2 / 8^1/6

2^x = 4

2^x = 2^2

x =2

Question 2:

Answer: 50

Step-by-step explanation:

8^1/3/5^-2

= 2/5^-2

= 2/1/5^2

= 2*  5^2/1

= 2 * 5^2

= 2 * 25

= 50

Answer:

A. x ≤ -\frac{19}{13}

Step-by-step explanation:

-9x + 2 > 18 or 13x + 15 ≤ -4

-9x > 16 or 13x ≤ -19

x > -\frac{16}{9} or x ≤ -\frac{19}{13}

From the choices given, only x ≤ -\frac{19}{13} proves to be correct answer.

What you are trying to do, I don't know. I will combine them for you.

\displaystyle \frac{6}{x-1} - \frac{5x}{4} \\ \\ = \frac{4(6)}{4(x-1)} - \frac{5x(x-1)}{4(x-1)} \\ \\ 
= \frac{24}{4(x-1)} + \frac{-5x(x-1)}{4(x-1)}  \\ \\
= \frac{24}{4(x-1)} + \frac{-5x^2+5x}{4(x-1)}  \\
= \frac{24 - 5x^2 + 5x}{4(x-1)}

9)

\displaystyle 
\frac{3}{x+7} + \frac{4}{x-8} \\ \\ = 
\frac{3(x-8)}{(x+7)(x-8)} + \frac{4(x+7)}{(x+7)(x-8)} \\ \\ =
\frac{3x-24}{(x+7)(x-8)} + \frac{4x+28}{(x+7)(x-8)} \\ \\ =
\frac{3x-24}{(x+7)(x-8)} + \frac{4x+28}{(x+7)(x-8)} \\ \\ =
\frac{7x + 4}{(x+7)(x-8)}
