Point B on the number line shows Benny's score after the first round of a quiz: A number line is shown from negative 10 to 0 to positive 10. There are increments of 1 on either side of the number line. The even numbers are labeled on either side of the number line. Point B is shown on 2. In round two, he lost 6 points. Which expression shows how many total points he has at the end of round two?

-4

Step-by-step explanation:

I have taken the liberty of drawing (although pretty badly) the number line and attaching it below. As you can see from the picture, the number line moves up and down by values of 2. Also like mentioned, at the end of round one Benny ends up on point 2 which is represented by the letter B in the number line. Since in round 2 Benny lost 6 points we need to move to the left towards the negative values. Also since each line represents 2 numbers we would need to move 3 lines to the left (6/2 = 3) which would mean after round 2 Benny would end up on number -4

the correct option is 2.

step-by-step explanation:

according to the given information triangle abc is a right angle triangle with right angle at a. segment ab is 5 and segment ac is 7. point d is on segment bc and angles adb and adc are right angles.

it is given that triangles abd, cad, and cba are similar.

two triangles are similar if their corresponding sides are proportional.

in triangle cba, using pythagoras theorem

                      )

triangle abd and cba are similar,

                            (2)

triangle cad and cba are similar,

                      )

using (1), (2) and (3), we get

hence proved.

therefore option 2 is correct.
