Answer:

-600

Step-by-step explanation:

The rate of change of a function f(x) in a certain interval $(x_1,x_2)$ is the ratio between the change of the function and the change in the value of x:

$r=\frac{f(x_2)-f(x_1)}{x_2-x_1}$

The rate of change of a function tells how much the value of the function is changing per change in unit of x: therefore, for a linear function it corresponds to the slope of the line.

In this problem, the function f(x) is equal to the value of the business machine in dollars, while the variable x represents the number of years.

Here we are told that the machine was purchased for

$q=\$4500$

while its value decreases by $600 each year, so

$m=-600\$$

This means that the linear function that represents the value of the machine after x years is:

$y=4500-600x$

Therefore, the rate of change of the function is -600.

Determine the area of the composite figure.

MaRussiya [10]

Answer:

$110\ in^2$

Step-by-step explanation:

$1)\ A_1 = b * h_1 = 10 * 8 = 80\ in^2$

$2)\ A_2 = \frac{b*h_2}{2} = \frac{10*(14-8)}{2} = \frac{10*6}{2} = \frac{60}{2} = 30\ in^2$

$3)\ A = A_1 + A_2 = 80 + 30\ in^2 = 110\ in^2$

How to solve <img src="https://tex.z-dn.net/?f=2n%20%3D%5Cfrac%7B15%7D%7B2%7D" id="TexFormula1" title="2n =\frac{15}{2}" alt="2n

Zigmanuir [339]

Answer:

$2n=\dfrac{15}{2}$

Multiply both sides by 2:

$\implies 2 \cdot 2n=2 \cdot \dfrac{15}{2}$

$\implies 4n=15$

Divide both sides by 4:

$\implies \dfrac{4n}{4}=\dfrac{15}{4}$

$\implies n=\dfrac{15}{4}$

$\dfrac14=\dfrac{n}{5}$

Multiply both sides by 5:

$\implies 5 \cdot \dfrac14=5 \cdot \dfrac{n}{5}$

$\implies \dfrac54=n$

$\implies n=\dfrac54$
