The given function is
f(x) =
Comparing with
We get
a = 8, b = 2 & c = -5
Now if (h,k) is the vertex
then h =
Substituting the value of h in place of x in the function we get
k=
Now the vertex form of a quadratic equation is
f(x)= a(x-h)² + k
Substituting the values of a, h & k we get
f(x) = 8
The vertex form of f(x) = 8x² +2x-5 is
f(x) =
Answer
Hey
8x^2-4x
4x is the greatest common factor.
B answer
The amount that was invested 17 years ago is $2064.25.
The interest earned is $7935.75.
<h3>What is the amount invested 17 years ago?</h3>
The formula that would used to determine the amount that was invested 17 years ago is:
P = FV / (1 + r)^nm
Where:
- FV = Future value = 10,000
- P = Present value
- R = interest rate = 9.5 / 2 = 4.75%
- m = number of compounding = 2
- N = number of years = 17
10,000 / (1.0475)^(17 x 2) = $2064.25
Interest earned = 10,000 - 2064.25 = $7935.75

The answer is B. 4^2 hope I helped you...
explanation: both 4^7x4^-5 and 4^2 equals 16.
Answer:
|x – 42.80| = 12
Step-by-step explanation:
x – 42.80 = -12
x=30.8
x – 42.80 = 12
x=54.8
