456÷100=4.56
How to check your work: 456÷4.56=100
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
<u>Given</u>:
The given expression is 
We need to multiply the terms.
<u>Multiplication of the terms:</u>
Before multiplying the terms, first we shall find the factors of the quadratic equations.
Thus, we have;

Factor out the common terms, we get;

Let us cancel the common terms from the above expression.
Thus, we have;

Simplifying, the term, we get;

Now, we shall multiply the terms.
Hence, multiplying the terms, we get;

Thus, the multiplied value of the given expression is 
Step-by-step explanation:
The given inequality is

Subtract 10 from both sides


Divide both sides by 5 to get:

We draw a closed circle at 5 and draw the arrow to the left.
See it in the attachment.
To estimate, you would usually round to a significant figure
so, 20* 70=1400
The actual answer is 1521, so we know we are close
