1, -1 !!! i hope this helps (also download mathpapa :D )
Deandre = x
Kala = x + 6
Eric = 3(x+6)
x + x + 6 + 3(x+6) = 119
2x + 6 + 3x + 18 = 119
5x + 24 = 119
5x = 95, x = 19
Deandre has $19
Kala has 19 + 6 = $25
Eric has 3(25) = $75
X difference: 7-2 = 5
y difference: 11-10 = 1
Add up those results: 5+1 = 6
Answer Is 6
Answer:
5r+12
Step-by-step explanation:
Using an exponential function, it is found that it takes 5.42 years for the car to halve in value.
<h3>What is an exponential function?</h3>
A decaying exponential function is modeled by:

In which:
- A(0) is the initial value.
- r is the decay rate, as a decimal.
In this problem, the car depreciates 12% a year in value, hence r = 0.12 and the equation is given by:
.
It halves in value at t years, for which A(t) = 0.5A(0), hence:






t = 5.42.
It takes 5.42 years for the car to halve in value.
