Solving the expression $\frac{4-5i}{2+3i}$ we get $-\frac{7}{13}-\frac{22i}{13}$

So, Option A is correct.

Step-by-step explanation:

We need to solve the expression: $\frac{4-5i}{2+3i}$

Multiplying and dividing by 2-3i

$=\frac{4-5i}{2+3i}*\frac{2-3i}{2-3i}\\=\frac{4-5i*2-3i}{2+3i*2-3i}\\=\frac{4(2-3i)-5i(2-3i)}{(2)^2-(3i)^2}\\=\frac{8-12i-10i+15i^2)}{4-9i^2}\\We\,\,know\,\, i^2=-1\\=\frac{8-12i-10i+15(-1)}{4-9(-1)}\\=\frac{8-15-12i-10i}{4+9}\\=\frac{-7-22i}{13}\\=-\frac{7}{13}-\frac{22i}{13}$

So, solving the expression $\frac{4-5i}{2+3i}$ we get $-\frac{7}{13}-\frac{22i}{13}$

So, Option A is correct.

What is the Inverse Equation f(x) =6x-1 ?? please I need help!

Scrat [10]

Answer:

$f^{-1}(x)=\frac{x+1}{6}$

Step-by-step explanation:

So we have the function:

$f(x)=6x-1$

To find the inverse function, switch x and f(x), change f(x) to f⁻¹(x), and solve for f⁻¹(x). Therefore:

$f(x)=6x-1$

Switch:

$x=6f^{-1}(x)-1$

Add 1 to both sides:

$x+1=6f^{-1}(x)$

Divide both sides by 6:

$f^{-1}(x)=\frac{x+1}{6}$

And that's our answer :)
