Identify the domain and range of the relation. Use a mapping diagram to determine whether the relation is a function. {(−1, 5), (3, 4), (2, 5), (−1, −3)}

b

step-by-step explanation:

the total is 23.97. 0.25% is off so you have to subtracting 25% from 100% and you will get 75% if you convert it to decimal you will get 0.75. you have to find the original because the formula is % times original = total.so you have the total and the % so you just have to plug it in.

substitute,

circle 1 = 5

circle 2 = 20

circle 3 = 44

in this case no matter how you add, you will always get a perfect square..

hence proved

pls mark as brainliest

the solution, from the graphing of the two lines, is (3,2), i.e., x = 3, y = 2.
