3. Solve for x.<br> 3r +11<br> 9x - 14<br> Plss
Studentka2010 [4]

Answer:

x=12

Step-by-step explanation:

use midpoint theorem that said that the small line segment (3x+11) is half of the segment ( 9x -14)

2(3x +11) = 9x -14

6x +22 = 9x -14; distribute

6x -9x = -22-14; subtract 9x and 22 from both sides

-3x = -36; divide both sides by -3

x= 12

-25^-1/2 with explanation please
slavikrds [6]

Answer:

The simplified value of -25^{-\frac{1}{2}} is -\frac{1}{5}.

Step-by-step explanation:

As the given expression is

-25^{-\frac{1}{2}}

Lets simplify this expression step by step

As

-25^{-\frac{1}{2}}....[A]

\mathrm{Apply\:exponent\:rule}:\quad \:a^{-b}=\frac{1}{a^b}

25^{-\frac{1}{2}}=\frac{1}{25^{\frac{1}{2}}}

So, lets plug 25^{-\frac{1}{2}}=\frac{1}{25^{\frac{1}{2}}} in equation [A] i.e.  -25^{-\frac{1}{2}}....[A]

-25^{-\frac{1}{2}}....[A]

=-\frac{1}{25^{\frac{1}{2}}}        ∵ 25^{-\frac{1}{2}}=\frac{1}{25^{\frac{1}{2}}}

=-\frac{1}{5}           ∵ 25^{\frac{1}{2}}=5

Therefore, the simplified value of -25^{-\frac{1}{2}} is -\frac{1}{5}.
