Question

A 9 feet tall dragon ice sculpture is melting at a rate of 1.75 feet per hour. Write a linear function that represents this scenario.

Answer 1

Answer:

$y = 9 - 1.75x$

Step-by-step explanation:

Given

$Initial\ Height = 9ft$

$Rate = 1.75ft$ per hour

Required:

Determine the linear function

Let y represent the function and x represent the number of hours

The function can be represented with:

$y = Initial\ Height- Rate * x$

We used minus (-) in the equation because the question indicates that the height of the sculpture reduces.

So, we have:

$y = 9 - 1.75 * x$

$y = 9 - 1.75x$
