3. Solve for x. 3r +11 9x - 14 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

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

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

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

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 $-\frac{1}{5}$ .
