PLSSS HELP WILL MARK BRAINLIEST!! :) Reflections. if you don't kno don't put anything :) there's no graph :) If point P(2,-4) is reflected over the x-axis, determine the coordinates of the image.

(-2, -4)
(-4, 2)
(4, 2)
(2, 4)

(2,4)

Step-by-step explanation:

the x values stays the same because you are reflecting over its axis. the 4 becomes positive

Step-by-step explanation:

Algebra Explanation: If something is reflected over the x axis, the x coordinate's sign will stay the same while the y coordinate sign will switch.

Using this info, the answer will be (2,4)

Geometric Explanation: Point P is in Quadrant 4. If we reflect a point about the x axis, it can only go to Quadrant 1. Quadrant 1 has a positive x and positive y. So this eliminates the first 2 options.

Reflecting across a line will align the pre image and current image with each other. This means the x coordinate and y coordinate will stay in the same place. So (2,4) is the answer.

solution:

as, mean is defined as sum of all the observations divided by total number of observations.

and , median is mid value of the data whether arranged in ascending order or descending order.

consider, roadsters:

2,3,4,5,6,7,8,9

mean =

also, median= , because number of observations is even, so median is mean of two mid values.

now, coming to bandits

2,3,4,5,6

mean =  

median = 4, as number of observations is odd.

so, roadsters has greater median as well mean than bandits.

→option a is true about the repairs performed on 2 types of cars:

bandits have lower median and mean than roadsters.
