Which ordered pairs match the mapping diagram?

a) (1, 0), (7, 2), (3, 4), (-1, 1), (-7, -6)

b) (0, 1), (2, 7), (3, 4), (-4, 1) , (-6, 7)

c) (0, 1), (0, 4), (0, 7), (2, 7), (-6, 7)

d) (0, -1), (2, -7), (-3, 4), (4, 1), (6, 7)

step-by-step explanation:

1. practice, practice & more practice

2. review errors

3. master the key concepts

do not try to memorise the processes.

4. understand your doubts.

5. create a distraction free study environment

6. create a mathematical dictionary

7. apply maths to real world problems.

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 : )
