Kisachek [45]

Answer:

RS + ST = RT

23 - 2x + 9x - 5 = 39

18 + 7x = 39

7x = 39 - 18 = 21

x= 21/7

x = 3

RS = 23 - 2x (given)

RS = 23 - 2(3)

= 23 - 6

RS = 17

If<br> f(x) = 13x + 1, then<br> f-1(x) =

amid [387]

Answer:

(x-1)/13

Step-by-step explanation:

y = 13x+1

To find the inverse, exchange x and y

x = 13y+1

Solve for y

Subtract 1 from each side

x-1 =13y+1-1

x-1 = 13y

Divide each side by 13

(x-1)/13 = y

The inverse is (x-1)/13
