Answer:
Step-by-step explanation:
You would do 21,000×0.20, which equals 4,200. Since 4,200 equals 20% of 21,000, then you would do 21,000-4,200, which equals 16,800. So the car is worth $16,800 dollars this year.
 
        
             
        
        
        
<span>Alright, here's your answer.
y-intercept is computed (not found) by assigning x = 0 and computing y: here that is f(0) = Log(2*0 + 1) – 1 = Log(1) – 1 = 0 – 1 = -1 
y-intercept is (0, -1) 
x-intercept is computed by solving f(x) = 0 for x: here that is 
0 = Log(2x + 1) – 1 → 1 = Log(2x + 1) 
Assuming the Log cited is base 10, then 10^1 = 10^Log(2x + 1) = 2x + 1 
That’s 10 = 2x + 1 
Therefore 9 = 2x 
x = 9/2 = 4.5 
Check this result in the original equation, I did! 
Your answer is - x-intercept is (4.5, 0)
I hope I helped! :)

Answer:
12=12
Step-by-step explanation:
4.2÷0.35=420÷35
12=12
12-12=0
0=0
