Select the points you need to calculate the average rate of change from the beginning of the slide to when the slide has covered a horizontal distance of 15 feet.

a (0, 80)

b (5, 40)

c (10, 20)

d (15, 10)

The correct options are A and D.

Explanation:

If we want to find the average rate of change from the beginning of the slide to when the slide has covered a horizontal distance of 15 feet, the we have to find the initial point and point where horizontal distance is 15 feet.

In the given graph x axis represents the horizontal distance and y axis represents the height of the slide.

From the figure it is crealy noticed that the coordinates of the points are (0,80), (5,40), (10,20), (15,10) and (20,5).

Since at the initial point the horizontal distance is 0, so the coordinates of initial point is (0,80).

The coordinates of the point where horizontal distance is 15, are (15,10).

Therefore to find the slope or average rate of from the beginning of the slide to when the slide has covered a horizontal distance of 15 feet the required points are (0,80)and (15,10). So option A and D are correct.

A and D

Just took it. Edg 2020. Hope this helps :)

this is a very good question

step-by-step explanation:

i got a hair cut today from my mom not to flex just to flex kim jon un is one rad fellow i'd say you'd need to take the hairline in kinda like a box shape like someone rammed a lego brick into your head. from there you really need to take the top up keeping with that boxy aesthetic, finally coat the whole thing with gel if your country economics are failing or whatever you can just coat it with the starving children's food rations. about 5 orphans per strand is a good ratio. good luck with the fresh cut my dude

in simplified version   it would be x ≤-4

step-by-step explanation:

multiply each term in x ≤-4 by -1
