*timed* answer. how is the graph of y=1/3x related to its parent function y=1/x a. it is horizontally stretched by a factor of 3 and reflected over the x-axis. b. it is horizontally stretched by a factor of 3 and reflected over the y-axis. c. it is horizontally compressed by a factor of 3 and reflected over the x-axis. d. it is horizontally compressed by a factor of 3 and reflected over the y-axis.

the graph was compressed by a factor of three but the only way it would reflect over an axis is if there was negative change.

for example if the graph was y=-1/3x the graph would have reflected over the y-axis or the x-axis.

hope this ! :

perimeter = 10 +  √10  units

explanation:

first, we will need to get the length of each line using the distance formula which is as follows:

distance = 

1- length of ab:

ab =   = 5 units

2- length of ac

length of ac is the same as ab = 5 units

3- length of bc:

bc =   =  √10  units

now, we can get the perimeter by adding the side lengths as follows:

perimeter = 5 + 5 +  √10

perimeter = 10 +  √10  units

hope this : )
