Answer:

the sequence is the a geometric sequence because the terms has a common ratio. the common ratio = -80 / 200 = -2 / 5common ratio = 32 / -80 = -2 /5

so the next to term can be solve multiplying the last term with the common ratio

x = -12.8 ( -2 / 5)x = 5.12

y = 5.12 ( - 2 / 5)y = -2.048

Step-by-step explanation: HOPE THIS HELPS!!

The exponential decay graph shows the expected depreciation for a new boat, selling for $3500, over 10 years a. Write an exponen
Alex Ar [27]
For the answer to the question above,  
<span>V(n) = a * b^n, where V(n) shows the value of boat after n years. 
V(0) = 3500 
V(2) = 2000 

n = 0 
V(0) = a * b^0 = 3500 
a = 3500 

V(2) = a * b^2 
2000 = 3500 * b^2 
b = sqrt (2000/3500) 
b ≈ 0.76 

V(n) = 3500 * 0.76^n 

We can check it for n = 1 which is close to 2500 in the graph: 
V(1) = 3500 * (0.76)^1 
V(1) = 2660 

And in the graph we have V(3) ≈ 1500, 
V(n) = 3500 * (0.76)^3 ≈ 1536 

Now n = 9.5 
V(9.5) = 3500 * (0.76)^(9.5) 
V(9.5) ≈ 258</span>

Solve for x 10x+1=12x-5
Verdich [7]

Answer:

x=3

Step-by-step explanation:

1) 10x+1-1 = 12x-5-1, this becomes a new equation

Equation: 10x = 12x-6

2) 10x-12x = 12x-12x-6, this become a new equation

Equation: -2x = -6

3) Divide both sides by -2: -2x/2 = -6/2

4) Once you simplify, you will get x=3

Hope this helps!
