Here we are given the x intercepts at x=3 and x=9
So let us try to make quadratic equation for this using given information.
We have factors in the form (x-a)(x-b)
where a and b are x intercepts given to us.
So rewriting in factored form:

Now let us simplify it:

Let us find the vertex now,
For a quadratic equation of the form:

For x coordinate , we have the formula,

So using this formula for our equation,

So x = 6
Answer: The x-coordinate of the parabola's vertex is 6.
728 ÷ 3
= 242.66667
Hope I can help you, brainliest answer? :)
Answer:

Step-by-step explanation:
We have been given that Camacho is buying a monster truck. The price of the truck is x dollars, and he also has to pay a 13% monster truck tax. We are asked to find the total amount paid by Camacho for the monster truck.
The total cost of monster truck would be x plus 13% of x.



Therefore, Camacho paid
dollars in total for the truck.
Answer:
5.9x + 1.4
Step-by-step explanation:
5.5 + 2.1x + 3.8x - 4.1
= 5.9x + 1.4
