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

Can anyone do this for me?! I don’t understand

gayaneshka [121]

Answer:

Step-by-step explanation:

Q no 4 :

4, 8

1, 5

3, 7

2, 6

Q no 5:

(a)

10x + 1 = 12x - 5

1+5= 12x - 10x

2x = 6

x = 6/2

x = 3

(b)

11x - 15 + 5x - 13 = 180 (angles on a straight line)

11x + 5x - 15 - 13 =180

16x - 27 = 180

16x = 180 + 27

16x = 207

x = 207 / 16

x = 12.9375
