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
If it is the normal rate, there are 12 angelfish
Answer:
Solve a system of equations with two unknowns x and y
where x is the rental price for the movie and y is the rent for video games
7x + 9y = 73
5x + 3y = 29
Solving the result: x = $ 1.75, y = $ 6.75

Hello!!
Obviously, there are many possibilities for a real world problem. But, here's one option.
"Jeanette owes her friend, Debbie, a sum of money that is a multiple of 8. During the summer, Jeanette earns 60 dollars by selling cookies at a bake sale. After paying Debbie back for the borrowed sum of money, Jeanette has 28 dollars left. What was the sum of money divided by 8 that Jeanette owed Debbie?"
Hope this helps!! Let me know if you have ANY questions.
