What is 3/2 x + 30 degrees

jekas [21]

Sum of internal angles of any triangle = 180∘

∴x + 2x + 3x = 180∘
∴6x = 180∘
∴ x = 30∘

So the angles are: 30∘, 60∘ and 90∘

What is the Inverse Equation<br><br>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 :)
