Distribute...
99 - 9k = 9k - 27
Add 27 to both sides
126 - 9k = 9k
Add 9k to both sides
126 = 18k
Divide by 18
k = 126 / 18 = 7

A brand new car costs $18,000, this price depreciates at 25% every year, how much would the car be after 12 years? 20 years?

Snezhnost [94]

Answer:

C(12)=$570.18

C(20)=$57.08

Step-by-step explanation:

Exponential Decay Function

The exponential function is often used to model natural growing or decaying processes, where the change is proportional to the actual quantity.

An exponential decaying function is expressed as:

$C(t)=C_o\cdot(1-r)^t$

Where:

C(t) is the actual value of the function at time t

Co is the initial value of C at t=0

r is the decaying rate, expressed in decimal

The depreciation of goods is often modeled as an exponential function. The new car costs $18,000 and its price depreciates at r=25%= 0.25 every year.

The depreciation model is:

$C(t)=18,000\cdot(1-0.25)^t$

Operating:

$C(t)=18,000\cdot 0.75^t$

At t=12 years, the price will be:

$C(12)=18,000\cdot 0.75^{12}$

C(12)=$570.18

At t=20 years, the price will be:

$C(20)=18,000\cdot 0.75^{20}$

C(20)=$57.08

Anna plants peas in 3/8 of her garden and herbs in 1/8 of it. she divides the rest of the garden into 6 sections. what fraction

Scrat [10]

To find this answer you will first subtract the two fractions from the original size of one whole garden. After that take the remaining amount and break it into six sections. This answer would represent the fraction of the original garden that is in each section. Here are the steps:
1. Add the two fractions together to get 4/8 or 1/2. This means that half of it is left.

2. Take the 1/2 that remains and divide it by 6 (1/2 divided by 6 = 1/2 x 1/6). The answer is 1/12.

3. 1/12 of the original garden is in each section.

What is the equation of the line?

Oksi-84 [34.3K]

First find the slope of the line. Slope is defined as the change in y over the change in x.

$m = \frac{y_2 - y_1}{x_2 - x_1}$

Find two ordered pairs and plug them into the slope formula.

After looking at the graph, I found two points: (0, 1) and (4, 4)

$\frac{4 - 1}{4 - 0} = \frac{3}{4}$

Now find where the line intersects the y-axis.

After looking at the graph, I found out that the line intercepts the y-axis at
(0, 1)

Now build the slope-intercept equation.

General form: y = mx + b
Where m is the slope and b the y-intercept

So, the answer is y = 3/4m + 1
