The equation of the value of the car over a year is 2357.14x + y = 33,000. Then the value of the car 4 years after it was purchased is $23571.43.
<h3>What is the linear system?</h3>
A Linear system is a system in which the degree of the variable in the equation is one. It may contain one, two, or more than two variables.
A new car is purchased for $33,000 and overtime its value depreciates by one half every 7 years.
Then the value of the car is given by the linear equation. Then the line is passing through (0, $33,000) and (7, $16,500). Then we have
Let y be the value of the car and x be the number of years. Then we have
Then the value of the car 4 years after it was purchased, to the nearest hundred dollars will be

Hello!
Usually systems of equations have one equation that will show the value of one variable in relation to their other, such as y=2x.
The other equation will usually show the two variables in relationship to another number, such as x+y=15.
To make a system of equations for this point, we need to show one variable’s value in relation to the other. We could put that x=2/3y.
Now we show x and y in relation to another number. We could put that x+y=-5.
Note that we could add y intercepts and extra coefficients to these equations, but for now I am keeping it simple.
Now we have a possible system of equations.
x=2/3y
x+y=-5
When solving for the values of x and y, you could substitute the first equation for x in the second equation to solve.
I hope this helps!
Answer:
<em>32 units² </em>
Step-by-step explanation:
= 4(2 + 2 + 6) ÷ 2 = 20
= (2 × 2) ÷ 2 = 2
= 2² = 4
= 2 × 6 ÷ 2 = 6
A = + + + = <em>32 units²</em>
Answer:
A. $1 less
Step-by-step explanation:
24 divided by 8 (unit rate) = $3
28 divided by 7 = $4
4-3=1
