Answer:
A exponential equation is usually of the form f(x)=a (1±r)ˣ.
Our limitation: Initial Vale is 500.
Let's look at our options:
#1- Initial Value of 1000 --- WRONG!
#2- Initial Value of 1000 --- WRONG!
#3- Initial Value of 500 ---- Maybe
#4- Initial Value of 500 ---- Maybe
Let's look at 3 and 4:
#3- Fits Our Form of f(x)=a (1±r)ˣ ---- CORRECT!
#4- Does not fit Our Form of f(x)=a (1±r)ˣ, It's to the 2nd power, not the x power! ---- WRONG!
Hence, #3 Is correct!
Step-by-step explanation:
Well, I hope you understood, and I'd gladly explain anything that didn't make sense. A brainliest would be appreciated, thank you!

Answer:
D) (5x - 3) (25x^2+ 15x + 9)
Step-by-step explanation:
X=4. 4/2=2 and 8/4=2 making the equations equal
Answer:
x = - 3 ± √27 or if you want it in decimal form correct to nearest hundredth:
x = -8.20, 2.20.
Step-by-step explanation:
x^2 + 6x - 18 = 0
this will not factor so we use completing the square:
x^2 + 6x = (x + 3)^2 - 9 so:
(x + 3)^2 - 9 - 18 = 0
(x + 3)^2 = 27
x+ 3 = ±√27
x = - 3 ± √27
<h3>Given Equation:</h3>
25 - 5x = 5( -x + 5 )
<h3>Solution:</h3>
25 - 5x = -5x + 25
or, 25 - 25 - 5x + 5x = 0
or, x = 0
<h2>Answer:</h2>
<u>Option B. x = 0</u>
<h3>To Check:</h3>
25 - 5x = 5 ( -x + 5 )
or, 25 - 5(0) = 5 ( 0 + 5 )
or, 25 - 0 = 0 + 25
or, 25 = 25
LHS = RHS
Hence, Verified.
