Answer: 16/81 (x-10)^2 -4
Step-by-step explanation:
To write a vertex equation with just a point and the vertex, you have to figure out the variables.
In vertex form, the equation is y = a (x-h)^2 + k
Your y is 12, x = 1, h = 10, and k = -4
Plug everything into equation
12 = a (1 - 10)^2 -4
12 = a (-9)^2 - 4
12 = 81a - 4
16 = 81a
16/81 = a
Now you know what the 'a' value is.
If you graph 16/81 (x-10)^2 -4 , you will get a point at (1,12) and a vertex of (10,-4)!
I hope this helps!
<span>So, "2.5 more than the quotient of h and 3 is w" becomes 2.5 + h/3 = w. </span>
1-2 = -1
If that's what u mean
Answer:
480
Step-by-step explanation:
All you have to do is multiply all the numbers together.
12 * 4 * 5 * 2 = 480
