1. alexander’s grandparents get him a puppy for his thirteenth birthday, and he names the puppy boomer. when boomer is 1 month old, he weighs 4 pounds. when he is 2 months old, he weighs 7 pounds. in this relationship, x represents boomer’s age (in months), and y represent her weight (in pounds). 1a.) graph the two points for this relationship and the line passing through them on the coordinate plane. (2 points).

step-by-step explanation:

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.
