Answer:

x = 2

Step-by-step explanation:

5x + 3 = 7x - 1

Combine like factors by subtracting both sides by 7x and 3.

-2x = -4

Divide both sides by -2.

x = 2

The solution is 2.

2. Perimeter = 8dm + 8dm + 5dm + 5dm

= 26dm

3. Perimeter of rectangle = 3mm + 3mm + 7mm + 7mm = 20mm

4. Perimeter of triangle = 8dm + 12dm + 10dm = 30dm

If f(x) = 5x – 1, then f^-1(x)=
Umnica [9.8K]

Answer:

\boxed{\sf \ \ \ f^{-1}(x)=\dfrac{x+1}{5} \ \ \ }

Step-by-step explanation:

hello

f(x)=5x-1

what can we say about f^{-1}(x) ?

(fof^{-1})(x)=x=f(f^{-1}(x))=5f^{-1}(x)-1

so

5f^{-1}(x)-1=x\\ 5f^{-1}(x)-1+1=5f^{-1}(x)=x+1 \ \ \ add \ \ 1\\   f^{-1}(x)=\dfrac{x+1}{5} \ \ \ divide \ \ by  \ \ 5

hope this helps
