Answer:

V(t)=28,000(0.75)^t.

$8859.375

Step-by-step explanation:

Please find the attachment for the function.

We have been given that a car sells for $28,000.The car  depreciates such that each year it is worth 3/4 of its value from the previous year. We are asked to find the model for the value V of the car after t years.

We know that an exponential function is in form y=a(b)^x, where,

a = Initial value,

b = Growth or depreciation rate.

Since each year the car worth 3/4 of its value from the previous year, so its value is depreciating and b=\frac{3}{4}=0.75.

Therefore, our required function would be V(t)=28,000(0.75)^t.

To find the value of car after 4 years, we need to substitute t=4 in our function as:

V(4)=28,000(0.75)^4

V(4)=28,000(0.31640625)

V(4)=8859.375

Therefore, the value of the car after 4 years would be $8859.375.

What is the solution to the system of equations?<br><br> 6x – 9y = 16<br><br> 2x – 3y = 7
kifflom [539]
The first step for solving this problem is to multiply both sides of the bottom equation by -3.
\left \{ {{6x-9y=16} \atop {-6x + 9y = -21}} \right.
Add the two equations together.
6x - 9y - 6x + 9y = 16 - 21
Eliminate the opposites.
-9y + 9y = 16 - 21
Remember that the sum of two opposites equals 0,, so the equation becomes the following:
0 = 16 - 21
Calculate the difference on the right side of the equation.
0 = -5
This means that the statement \left \{ {{6x-9y=16} \atop {2x-3y=7}} \right. is false for any value of x and y. That means that the answer to your question is (x,y) ∈ ∅,, or no solution.

The second and last one.

The second one multiplies the cost of each type of ticket by two, therefore saying that you wanted to buy two of each type of ticket.
