Answer:

B.  f^{-1}(x)=\frac{x-4}{5}

Step-by-step explanation:

To find the inverse of a function/equation:

  1. Replace f(x) with y: y=5x+4
  2. Switch x and y: x=5y+4
  3. Solve for y: x-4=5y   ->    y=\frac{x-4}{5}
  4. Write in standard inverse notation: f^{-1}(x)=\frac{x-4}{5}

I hope this helps!!

Answer:

43.25

Step-by-step explanation:

Since sides DF and FE are congruent, their opposite angles D and E are also congruent.

m<D + m<E + m<F = 180

x + x + 93.5 = 180

2x = 86.5

x = 43.25

Select each expression that is equivalent to 3n+6 select all that apply. Explan.
arsen [322]
A, C. A is obviously correct because it’s the e same thing and C you combine like terms (2n+n=3n,2+4=6,=3n+6) it’s not B because it’s not 18, it’s not D because you’d get 3n+18 and it’s not E because you’d get 3n+12, meaning the only correct answers are A and C
