The approximate original price of the car is $23032
<h3>How to determine the original price?</h3>
The given parameters are:
Rate, r = 8%
Price at 4 years old = 16,500
An exponential function is represented as:
y = a(1 - r)^x
Where a represents the initial value
This gives
y = a(1 - 8%)^x
Evaluate
y = a(0.92)^x
At 4 years old, we have:
16500 = a(0.92)^4
Divide both sides by (0.92)^4
a = 23032
Hence, the approximate original price of the car is $23032

Since both equations give the value of y, therefor y = y. You simply substitute y with its corresponding equation.
y = y
x + 9 = 2x + 1 *we need to find the value of x to get the value of y.
x - 2x = 1 - 9
-x = -8
-1x/-1 = -8/-1
x = 8
Substitute x with its value to get y.
Equation S: y = x + 9 </span>⇒ y = 8 + 9 ⇒ y = 17
Equation T: y = 2x + 1 ⇒ y = 2(8) + 1 ⇒ y = 16 + 1 ⇒ y = 17
<span>x+9=2x+1
</span>17 = 17
Answer:
8
Step-by-step explanation:
Answer:
y=2 is increasing.
Step-by-step explanation:
y=2 means to move from (0,0) on the graph to (0,2). Since it is positive it is increasing. Idk if the x in y=2x changes the outcome or not. Hope this helps!
