The population seems like a young age group.
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.

Step-by-step explanation:
I don't know exactly word from word what your choices look like...
but I can describe per each box what happened in my own words:
First box: They multiply first equation by 3 and the second equation by 2 to obtain the equations in that first box.
Second box: They subtracted the two equations in the first box to obtain 1x+0y=2 which means 1x=2 or x=2 (this is called solving a system by elimination
Third box: They used their first original equation (before the multiplication manipulation) and plug in the value they got for x which was 2 giving them 3(2)-2y=10
Fourth box: They simplified the equation 3(2)-2y=10 by performing the multiplication 3(2) giving them 6-2y=10
Fifth box: They subtracted 6 on both sides giving them -2y=4
Sixth box: They divided both sides by -2 giving them y=-2
I will summarize then what I wrote above:
1st box: Multiplication Property of Equality
2nd box: Elimination
3rd box: Substitution (plug in)
4th box: Simplifying
5th box: Subtraction Property of Equality
6th box: Division Property of Equality
Answer:
3
Step-by-step explanation:
-5y + 4 = -11 Get rid of the numbers to get y alone.
-5y +4 minus 4 = -11 minus 4 Here you are removing the 4 from the left
-5y = -15 Now you will have to get rid of the -5
-5y/(-5) = -15/(-5)
y = 3
Answer:
Let x = the hours needed for Wanda to catch up to Hector.
Hector has already completed 18 miles. Hector travels at 12 miles per hour.
After x more hours, Hector will travel
18 + 12x miles
Wanda travels at 16 miles per hour. In x hours, she travels
16x miles
If Wanda catches up to Hector, then
16x = 18 + 12x
4x = 18
x = 4.5 hours
Answer: 4 hours, 30 minutes (or 4.5 hours)
