Find the inverse of f(x)

FinnZ [79.3K]

Answer:

$\huge\boxed{A.\ f^{-1}(x)=\dfrac{x-3}{5}}$

Step-by-step explanation:

$f(x)=5x+3\to y=5x+3\\\\\text{exchange}\ x\ \text{with}\ y\\\\5y+3=x\\\\\text{solve for}\ y\\\\5y+3=x\qquad|\text{subtract 3 from both sides}\\\\5y+3-3=x-3\\\\5y=x-3\qquad|\text{divide both sides by 5}\\\\\dfrac{5\!\!\!\!\diagup y}{5\!\!\!\!\diagup}=\dfrac{x-3}{5}\\\\y=\dfrac{x-3}{5}\to f^{-1}(x)=\dfrac{x-3}{5}$

A tall tree has a shadow that measures 40 feet. Next to the tree is a man whose shadow measures 4

o-na [289]

<h3>The height of the tree is 55 feet</h3>

<em><u>Solution:</u></em>

Let,

Height of tree = x

Shadow of tree = 40 feet

Height of man = 5.5 feet

shadow of man = 4 feet

Set up a proportion comparing the height of each object to the length of the shadow.

$\frac{\text{ Height of tree}}{\text{ Shadow of tree }} = \frac{\text{ Height of man}}{\text{ shadow of man }}$

Therefore,

$\frac{x}{40} = \frac{5.5}{4}\\\\x = 5.5 \times 10\\\\x = 55$

Thus height of the tree is 55 feet
