Y = x^2 - 6x + 7
a = 1
b = -6
c = 7
Before you get the A.O.S, you must first solve for the vertex.
The vertex formula is \frac{-b}{2a}
Plug in the numbers:
-(-6) / 2(1)
--6 = 6 and 2*1 = 2
6/2
Vertex (or x) = 3
Now you have to plug in the x in order to find the vertex (or y)
Your equation should now look like this;
y = (3)^2 - 6 (3) +7
Solve each part separately and then add it up...
3^2 = 9
-6 * 3 = -18
+7
9 - 18 + 7
A.O.S (or y) = -2

Answer:</h3>
A. 3
<h3>
Step-by-step explanation:</h3>
Fill in the given values in the formula (h=0, r=48) and solve for t.
... 0 = 48t -16t²
... 0 = 16t(3 -t)
This is true for t = 0 and for t = 3.
The ball will take 3 seconds to hit the ground.
An expression is defined as a set of numbers, variables, and mathematical operations. The term that best describes 3 is coefficient.
<h3>What is an Expression?</h3>
In mathematics, an expression is defined as a set of numbers, variables, and mathematical operations formed according to rules dependent on the context.
The value of 3 in the expression, 9 + 4(x + 2) - 3x, is that it is the coefficient of x in the third term.
Hence, the term that best describes 3 is coefficient.

First, we have to find 20% of $40.00 To find it, multiply 0.20 x $40.00 and you get $8
Now, take away the 20% away from $40.00
$40.00 - $8.00 = $32.00
Next, find 5% of $32.00 We have to multiply 0.05 x $32.00 and you get $1.60
We had $32.00 after the 20% discount, so add $32.00 + 1.60
Lydia paid $33.60 for her shirt.
