Function to inverse function f(x) =2x/3-17

ZanzabumX [31]

Answer:

Inverse function is $f^{-1}(x)=\frac{3}{2}x+\frac{51}{2}$ .

Step-by-step explanation:

Given function is $f\left(x\right)=\frac{2}{3}x-17$ .

Now we need to find the inverse of the given function.

Step 1: replace f(x) with y

$y=\frac{2}{3}x-17$

Step 2: switch x and y

$x=\frac{2}{3}y-17$

Step 3: solve for y

$x=\frac{2}{3}y-17$

$x+17=\frac{2}{3}y$

$\frac{3}{2}(x+17)=y$

$\frac{3}{2}x+\frac{51}{2}=y$

Hence required inverse function is $f^{-1}(x)=\frac{3}{2}x+\frac{51}{2}$ .

Answer:

THE CORRECT OPTION IS C) Δ RST $\sim$ Δ UVW ; $\frac{5}{6}$

Step-by-step explanation:

i) ∠ WUV = ∠ TRS ( same angle = 32 )

ii) $\frac{TR}{UW} = \frac{RS}{VU} = \frac{15}{18} = \frac{10}{12} = \frac{5}{6}$ ;

Hence it is proved that

Δ RST $\sim$ Δ UVW
