What is the range of the following set? (-2,4), (0,3), (1,6), (-1,2)
a. (4,0,6,-1)
b. (-2,0,1,-1)
c. (-2,4,0,3,1,6,-1,2)
d. (4,3,6,2)
e. (-2,3,1,2)

  d.  (4,3,6,2)

Step-by-step explanation:

The list of second numbers of the ordered pairs is the range.

___

The second number of the first pair is 4; the second number of the second pair is 3. The only 4-number answer choice containing these two numbers is (d). You don't even have to work the whole problem to make the proper choice.

distance covered by pamela in 9 l of fuel = 99km

let us apply unitary method here.

distance covered by pamela in 1 l of fuel =99/9 =11 km

now let us find distance covered by pamela if she has 12 l of fuel.

distance covered in 12 l = distance covered in 1 l of fuel * 12

we know that distance covered by here in 1 l is 11 km.

so distance covered in 12 l of fuel = 11*12 = 132 km.
