Answer:

$\large \boxed{e^{i\pi}+1=0}$

Step-by-step explanation:

Hello, please consider the following.

For any x real number,

$e^{ix}=cos(x)+i\cdot sin(x)\text{, right? So}\\\\e^{i\pi}=cos(\pi)+i\cdot sin(\pi)\\\\e^{i\pi}=-1+i\cdot 0=-1\\\\\text{ We add 1 to both sides of the equation.}\\\\\large \boxed{e^{i\pi}+1=0}\\$

Hope this helps.

Do not hesitate if you need further explanation.

Thank you

First, subtract 4 on both sides:-

$\tt{3x=28-4}$

$\tt{3x=24}$

Divide by 3 on both sides:-

$\dashrightarrow\bigstar\boxed{\boxed{\bold{x=8}}}\dashleftarrow$

Write an equation for the line below. Show work

Gekata [30.6K]

x=3 is your answer. This is because it only crosses the x-axis and this occurs at positive 3. y=3 on the other hand would be a horizontal line that only touches positive 3 on the y-axis.
