H(x)=2x-4/3 o h^-1(x)= 3x-12/2 o h^-1(x)= 3/(2x-4) o h^-1(x)= 3x+4/2

Fed [463]

Answer:

$\large\boxed{h^{-1}(x)=\dfrac{3x+4}{2}}$

Step-by-step explanation:

$h(x)=\dfrac{2x-4}{3}\to y=\dfrac{2x-4}{3}\\\\\text{Exchange x to y and vice versa}:\\\\x=\dfrac{2y-4}{3}\\\\\text{Solve for y:}\\\\\dfrac{2y-4}{3}=x\qquad\text{multiply both sides by 3}\\\\2y-4=3x\qquad\text{add 4 to both sides}\\\\2y=3x+4\qquad\text{divide both sides by 2}\\\\y=\dfrac{3x+4}{2}$

Please help me find the angle! (link) Thank you!

Vlad [161]

So angle CBD and ABC are a linear pair, which means that the two angles are supplementary (add up to 180°). Using this info, we can solve the equation for x as such:

$6x-60+8x+16=180\\ 14x-44=180\\ 14x=224\\ x=16$

Now that we got x, plug in 16 into x into 6x-60 and solve:

$6(16)-60\\ 96-60\\ 36$

In short, Angle ABC is 36°
