an oceanographer takes readings at the following positions relative to sea level: -2.48 kilometers, -2.83 kilometers, -2.70 kilometers, and 2.15 kilometers. Order the positions from the farthest sea level to the closest sea level.

for this case we must apply distributive property to the following expression:

the distributive property states that:

then, when applying the property we have to multiply the -2 for each term within the parenthesis:

sample answer: you can determine whether each element of the domain is paired with exactly one element of the range. for example, if given a graph, you could use the vertical line test; if a vertical line intersects the graph more than once, then the relation that the graph represents is not a function.

simple 80 pieces in 1 sercing so 80*47=3760+20=3780
