Answer:
Infinite solutions.
Step-by-step explanation:
If an equation is an identity, then there will be infinite solutions that the identity will have.
Let, us assume that an identity equation is given by
(a + b)² = a² +2ab + b².......... (1)
Now, putting any real values of a and b the identity will be satisfied.
Therefore, there are infinite solutions for an identity equation. (Answer)
Answer:
Both are true.
Step-by-step explanation:
A absolute always has a positive answer no matter what.
<h3>Answer</h3>
Sale Price = $36.4
Step-by-step explanation:
Sale Price = $36.4 (answer). This means the cost of the item to you is $36.4. You will pay $36.4 for a item with original price of $45.50 when discounted 20%. In this example, if you buy an item at $45.50 with 20% discount, you will pay 45.50 - 9.1 = 36.4 dollars.
The vertex form of the equation f(x) = x^2 - 3x, is f(x) = (x - 3/2)^2 - 9/5
<h3>How to rewrite the
quadratic function?</h3>
The quadratic function is given as:
f(x) = x^2 - 3x
Differentiate the function
f'(x) = 2x - 3
Set the function to 0
2x - 3 = 0
Add 3 to both sides
2x = 3
Divide by 2
x = 3/2
Set x = 3/2 in f(x) = x^2 - 3x
f(x) = 3/2^2 - 3 * 3/2
Evaluate
f(x) = -9/5
So, we have:
(x, f(x)) = (3/2, -9/5)
The above represents the vertex of the quadratic function.
This is properly written as:
(h, k) = (3/2, -9/5)
The vertex form of a quadratic function is
f(x) = a(x - h)^2 + k
So, we have:
f(x) = a(x - 3/2)^2 - 9/5
In f(x) = x^2 - 3x,
a = 1
So, we have:
f(x) = (x - 3/2)^2 - 9/5
Hence, the vertex form of the equation f(x) = x^2 - 3x, is f(x) = (x - 3/2)^2 - 9/5
