Please help! Will mark brainiest! Write an equation to mark each graph. (absolute value equation.)

asambeis [7]

Answer:

$y=-|x+1|+1$

Step-by-step explanation:

The h and k are the points of the vertex. The h is the one inside the absolute value bars. The k is on the outside. The h has to be the opposite sign from what is on the graph. For example, if the number on the the graph is -1, the number in the equation will have to be a positive 1. The number on the outside stays the same. If the number on the the graph is +1, the number in the equation will also be a positive 1.

Which data set could be represented by the box plot shown below? A horizontal boxplot is plotted along a horizontal axis marked

ludmilkaskok [199]

Answer:

(B)1,3,6,8,10,12,13,13,16,18,19

Step-by-step explanation:

In the box plot:

A left whisker extends from 1 to 6, therefore, the least value is 1.

The box extends from 6 to 16 and is divided into 2 parts by a vertical line segment at 12. Therefore:

The lower quartile is 6
The median is 12
The upper quartile is 16

The right whisker extends from 16 to 19, therefore the highest value is 19.

The set of data that satisfies these conditions where the numbers in bold are the 5- number summary is:

1,3,6,8,10,12,13,13,16,18,19

The correct option is B.
