1. Jackie buys a computer for $3600. For tax purposes, she declares a linear depreciation (loss of value) of $600 per year. Let y be the declared value of the computer after x years. If the linear relation of the depreciation model in this situation is given by 3600 - y = 600x

a. What is the slope of the line that models this depreciation?

b. Write a linear equation in slope-interception form to model the above depreciation equation.

c. Find the value of Jackie¿s computer after 4.5 years.

d. How many years will it take Jackie to fully depreciate her computer?

2. What kind of slope you would get if your employer decided to pay you the same salary whether you work overtime or not? Define the dependent and independent variables in this situation.

The techniques for solving linearequations and linear inequalities are similar, yet different. Explain and give an example of both a linearequation and a linear inequality that demonstrates this difference.
1.) Solve and check the linearequation.
5x - 5 = 30
A) {30}
B) {34}

D) {7}
2.) Solve and check th

With referrence to the last solutions u posted to me,may you please check no 1 I have a different solution from my workings.I not sure which one is correct,but I think mine might be.If so may u please edit the document because I failed to do so.I will use this over and over.

One fundamental difference between a linearequation and a linear inequality lies in the number of possible solutions. A linearequation has a finite (limited) number of solutions while the linear inequality has a range (set) of solutions.
I need an example of an equation and an inequality that expresses the above difference

After 2 minutes on a treadmill, Jenny has a heart rate of 82, after 3 minutes she has a heart of 86. Assume that there is a linearequation that gives her rate in h terms of time on the treadmill t. What is the equation and use it to predict her heart rate after 10 minutes on the treadmill.

1. Ture or false: The ordered pair (-1, 4) is a solution to the linear inequality:
-5x + 2y < = 13
