Answer:

Step-by-step explanation:
The standard form of a quadratic equation is 
The vertex form of a quadratic equation is 
The vertex of a quadratic is (h,k) which is the maximum or minimum of a quadratic equation. To find the vertex of a quadratic, you can either graph the function and find the vertex, or you can find it algebraically.
To find the h-value of the vertex, you use the following equation:

In this case, our quadratic equation is
. Our a-value is 1, our b-value is -6, and our c-value is -16. We will only be using the a and b values. To find the h-value, we will plug in these values into the equation shown below.
⇒ 
Now, that we found our h-value, we need to find our k-value. To find the k-value, you plug in the h-value we found into the given quadratic equation which in this case is 
⇒
⇒
⇒ 
This y-value that we just found is our k-value.
Next, we are going to set up our equation in vertex form. As a reminder, vertex form is: 
a: 1
h: 3
k: -25

Answer:
48
Step-by-step explanation:
First, substitute in 12 for x
2.4(12 ÷ 1/4)
Distribute 2.4 within the parenthesis
2.4 x 12 = 28.8
2.4 x 1/4 or 2.4 x 0.25 = 0.6
28.8 ÷ 0.6
Divide to get your answer:
48

Answer:
Triangles are congruent if they have the same sides.
Step-by-step explanation:
Triangles are congruent when all corresponding sides and interior angles are congruent.
To divide any fraction:1. Multiply the number by the reciprocal of the fraction.2. Simplify the resulting fraction if possible.3. Check your answer: Multiply the result you got by the divisor and be sure it equals the original dividend.
This point is not a solution to those lines.
