Answer:
a) The car will be worth $8000 after 2.9 years.
b) The car will be worth $6000 after 4.2 years.
c) The car will be worth $1000 after 12.7 years.
Step-by-step explanation:
The value of the car after t years is given by:

According to the model, when will the car be worth V(t)?
We have to find t for the given value of V(t). So





(a) $8000
V(t) = 8000

The car will be worth $8000 after 2.9 years.
(b) $6000
V(t) = 6000

The car will be worth $6000 after 4.2 years.
(c) $1000
V(t) = 1000

The car will be worth $1000 after 12.7 years.
Number 1s answer would be 2. and number 2s answer would be 2
Answer:


Step-by-step explanation:
<u>First, Let's solve for x in -2x+2y=-4:</u>

<u>Subtract 2y from both sides:</u>


<u>Divide both sides by -2:</u>


<u>Now, we'll substitute x=y+2 to 3x+3y=-18:</u>

→ let x=2+y

<u>Simplify:</u>

<u>Now, let's solve for y in 6+6y=-18</u>

<u>Subtract 6 from both sides:</u>


<u>Divide both sides by 6:</u>


<u>Now, substitute y=-4 into x=2+y:</u>

→ let y = -4


Therefore, x=-2 and y=-4.

Alright, lets get started.
3 feet = 1 yard
If we cube both sides of the equation, we will get the conversion into cubic yards
So,

27 cubic feet = 1 cubic yards
So, 1 cubic feet =
cubic yards
So, 360 cubic feet =
cubic yards
So, 360 cubic feet = 13.33 cubic yards
13.33 cubic yards of air can it circulate per minute. : Answer
