Hi there!
Looks like a lot of work is going on here.
Let's start by solving this equation for the x.
Step 1) Add -20y to both sides.
Step 2) Divide both sides by 5.
Final Answer:
Now, let's solve for y.
Step 1) Add -5x to both sides.
Step 2) Divide both sides by 20.
Final Answer:
Hope this helps! :D
Hint - When you have two variables in an equation, and you want to solve for one, the other will end up in your answer. :)
Answer:
y=35x+50
35*8=280
280+50=330
yes there will be 10 dollars left
I hope this is good enough:
An exponential decay function is:
f=ir^t, f=final amount, i=initial amount, r=common ratio, t=number of times ratio is applied...We can see the initial value is 17000 so all we really have to find is the common ratio, or "rate" as some call it :P If we look at the second point, when t=1 we can see:
14280=17000r
r=357/425
r=0.84
So in five years the SUV will be worth more than the car by:
17000(0.84^5)-12000(0.89^5)
$408.73 (to the nearest cent)
