Consider the following Argand-diagram
enter image description here
The y-axis is the imaginary axis and the x-axis is the real one. The complex number in question is
x+yi
To figure out θ, consider the right-triangle formed by the two-coordinates on the plane (illustrated in red). Let θ be the angle formed with the real axis.
tanθ=yx
⟹tan−1(yx)
The hypotenuse of the triangle will be
x2+y2−−−−−−√
Therefore,
Step-by-step explanation:
Since you didn't provide instructions, I am going to assune you are being asked to solve for x. To do this, just distribute and simplify.
2(4x-11)=10
Distribute the 2 to the expression (4x-11)
8x-22=10
Add 22 on both sides
8x=32
Divide by 8 on both sides
x=4
~I hope this helps!~
Could be wrong but try 6/3 then 2

Answer:
Step-by-step explanation:
We can find the inverse function of this excercise, isolating X and then changing the variables.
And now we change the variables and we get the inverse function:
