Answer:

2.5 days

Step-by-step explanation:

The planned production rate was ...

(4500 dresses)/(25 days) = 180 dresses/day

The actual production rate was ...

180 dresses/day + 20 dresses/day = 200 dresses/day

So the actual time required for production of 4500 dresses was ...

(4500 dresses)/(200 dresses/day) = 22.5 days

That is the time required was less by ...

25 days -22.5 days = 2.5 days

The company finished 2.5 days early.

If f(x) = 5x, what is f^-1(x)? F(x) = -5x of(x)- F(x) = 5* O F(x) = 5x

Oksana_A [137]

Answer:

f^-1 (x) = x/5

Step-by-step explanation:

f(x) = 5x

Replace f(x) with y

y= 5x

Exchange x and y

x = 5y

Solve for y

Divide each side by 5

x/5 = 5y/5

x/5 = y

The inverse is x/5
