A parabola intersects the x axis at x=2 and x=8. What is the x corrdinate

The x coordinate of the parabola's vertex is: 5

Step-by-step explanation:

Although you didn't finish the phrases of the question, if they were asking the x-value for the x-coordinate of the parabola's vertex, which is a typical question for this type of problem, recall that the vertex is position equidistant from the parabola's branches because the parabola is a symmetric figure.

Therefore we need to find the point half way between x = 2 and x = 8.

Notice that the distance between these two points is "6" units, and half of such distance is "3" units, so the vertex must be located 3 units to the right of 2 (or equivalently 3 units to the left of 8).

Therefore, the x-coordinate of this parabola's vertex is "5"

hi,

3. 12.15, you are correct.

4.2.01, your first digit is correct,

hope this !

points are handed out whenever you post answers.

brainliest answers are handed out by the person asking the question, so whether your answer is picked depends entirely on whether the asker bothers to pick

if you're asking about your rank, it depends on having a certain number of points and a certain number of brainliest answers. for example, at the time of this writing, i have 44338 points out of 15000 needed for the next (nearly triple the requirement! ) but i only have 24 out of 50 required brainliest answers. this number decays, meaning after a certain amount of time (i think about a month), the total number of brainliest answers you've earned doesn't count toward this total. (i've been stuck at the same rank for a long

the lesson to learn here is that you shouldn't worry about points or rank. chances are, no matter how good an answer you may provide, your efforts will go mostly unnoticed unless you focus on the newest/most active questions that get posted.
