Answer:

f^-1(x) = 1/5 x

Step-by-step explanation:

y = 5x

Exchange x and y to find the inverse

x = 5y

Solve for y

1/5x = y

The inverse is 1/5x

Answer:

$\Large \boxed{f^{-1}(x)=\frac{x}{5} }$

Step-by-step explanation:

f(x) = 5x

Replace f(x) with y.

y = 5x

Switch variables.

x = 5y

Divide both sides by 5.

$\frac{x}{5} =y$

The ratio of fishing boats to sailboats in a bay is 8:3. There are a total of 24 sailboats in the bay. How many fishing boats ar

lianna [129]

Answer:

The number of fishing boats in the bay = 64.

Step-by-step explanation:

The total number of sailboats = 24

Let us assume the number if fishing boats in the bay = m

⇒ Ratio of fishing boats to sailboats in a bay = m : 24.

Now, the ratio of fishing boats to sailboats in a bay is 8 : 3.

So, by the RATIO OF PROPORTION:

$\frac{m}{24} = \frac{8}{3} \implies m = \frac{8}{3} \times 24 = 64$

⇒ m = 64

Hence the number of fishing boats in the bay = 64.
