(04.01 lc) which of the sets of ordered pairs represents a function? (5 points) a = {(3, −5), (4, 6), (−3, 9), (2, 7)} b = {(2, 4), (−1, −7), (5, 6), (4, 3)}

Both A and B are representing a function.

Step-by-step explanation:

For the function A = {(3, −5), (4, 6), (−3, 9), (2, 7)}

Here , each input value (x-value : 3,4,-3,2) corresponds to a unique out put value (y-value : -5,6,9,7), that means A is a function.

B = {(2, 4), (−1, −7), (5, 6), (4, 3)}

Here, each input value (x-value : 2,-1,5,4) corresponds to a unique out put value (y-value : 4,-7,6,3), that means B is a function.

Hence, Both A and B are representing a function.

55

step-by-step explanation:

answer: 42

use a calculator to find that 845/73 = 11.575

the whole part of the answer is 11. multiply this by 73 to get 11*73 = 803.

subtract that result from 845 to get 845 - 803 = 42
