Christian purchased a new car. The value of the car is depreciating at a
1 answer:
18000 represents the price of the new car.
The value of the car in 6 years can be found by substituting 6 for the variable t, as follows:
In 6 years, it will be worth around $8359.27.
The equation for the car worth $20000 is this:
In 6 years, the other car will be worth $7542.99, so the car worth $18000 will have more value in 6 years.

There are several ways two triangles can be congruent.
<em> congruent by SAS</em>
<em> congruent by corresponding theorem</em>
In and
(see attachment), we have the following observations
--- Because O is the midpoint of line segment AD
--- Because O is the midpoint of line segment BC
---- Because vertical angles are congruent
---- Because vertical angles are congruent
Using the SAS (<em>side-angle-side</em>) postulate, we have:
Using corresponding theorem,
---- i.e. both triangles are congruent
The above congruence equation is true because:
- <em>2 sides of both triangles are congruent</em>
- <em>1 angle each of both triangles is equal</em>
- <em>Corresponding angles are equal</em>
