Answer:
y = -2x - 1
Step-by-step explanation:
X : Y
-2 : 3
<u>0 : -1</u>
1 : -3
3 : -7
First we have to find the y intercept we do that by looking at the table and finding what y = when x = 0
Then to find the slope we do the change in y over the change in x so when y changes by what what does x change by in this question it's when y goes down to or -2 x goes up one -2/1x = -2x
Answer:
$140.74
Step-by-step explanation:
Assuming this is a decaying exponential function, we can find a model for the depreciation in the form of v = a(b^t)
At t = 0, we get 5000 = a(b^0), which gives us a = 5000
At t = 1, we get 4000 = 5000b, such that b = 4/5
Now that our function is defined as v = 5000(4/5)^t, we can plug in t = 16 to solve for the value of the piano.
v = 5000(4/5)^16, which is approximately $140.74.
Answer:
The answer is "a" 5x-4(-3x+5)=-3
