Say the slope value of the next line -5x + 3y=30
1 answer:
<h3>Answer:</h3>
In this question, we're finding the slope of the line.
What this means is that we have to make the equation into slope intercept form.
Slope intercept form is: y = mx + b
In order to get the equation to slope intercept form, we have to get y by itself and solve from there.
Solve:
When you're done solving, you would see that answer choice C). m = 5/3 would be the correct answer.

Answer:
<em>C(12)=$570.18</em>
<em>C(20)=$57.08</em>
Step-by-step explanation:
<u>Exponential Decay Function</u>
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:
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:
Operating:
At t=12 years, the price will be:
C(12)=$570.18
At t=20 years, the price will be:
C(20)=$57.08
