Take the ln of both sides
remember
ln(a^x)=xln(a)
so

ln(2^x)=ln(22.5)
xln(2)=ln(22.5)
divide both sides by ln2
x=ln(22.5)/ln(2)
if you want to evaluate
use calculator
x=4.49185

Answer:

$x$

Step-by-step explanation:

$30-4x>6x-10$

Adding 10 to both sides.

$10+30-4x>6x-10+10$

$40-4x>6x$

Adding $4x$ to both sides.

$4x+40-4x>6x+4x$

$40>10x$

Dividing both sides by 10.

$\frac{40}{10}>\frac{10x}{10}$

$4>x$

∴ $x$

Can't figure it out!!

$\bf slope = {{ m}}= \cfrac{rise}{run} \implies 
\cfrac{{{ f(x_2)}}-{{ f(x_1)}}}{{{ x_2}}-{{ x_1}}}\impliedby 
\begin{array}{llll}
average\ rate\\
of\ change
\end{array}\\\\
-------------------------------\\\\
f(x)= \cfrac{1}{x} \qquad 
\begin{cases}
x_1=2\\
x_2=b
\end{cases}\implies \cfrac{f(b)-f(2)}{b-2}=-\cfrac{1}{10}
\\\\\\
\cfrac{\frac{1}{b}-\frac{1}{2}}{b-2}=-\cfrac{1}{10}\implies 
\cfrac{\frac{2-b}{2b}}{b-2}=-\cfrac{1}{10}\implies \cfrac{2-b}{2b}=-\cfrac{b-2}{10}
\\\\\\
$

$\bf \cfrac{2-b}{2b}=\cfrac{2-b}{10}\implies 20-10b=4b-2b^2\impliedby cross-multiplying
\\\\\\
2b^2-4b-10b+20=0\implies 2b^2-14b+20=0
\\\\\\
b^2-7b+10=0\implies 
(b-2)(b-5)=0\implies b=
\begin{cases}
\boxed{5}\\
2
\end{cases}$
