B. Because it makes a linear line.

The biggest rule for functions in a table is that none of the numbers in the X column are repeating. But for the Y column, it is okay to have repeats.

When you look at the answer choices, you could eliminate B, C, and D because of repeats in the x column.

A IS A FUNCTION because all the numbers in the x column are different

B is NOT A FUNCTION because in the x column, there are 2 3's

C is NOT A FUNCTION because in the x column, there are 2 -5's and 2 -10's

D is NOT A FUNCTION because there are 2 20's

Your answer would be A.

Two angles that have the sum of 180 degrees

Two angles that have the sum of 180 degrees are supplementary angles. If you need to find angle A, you just need to subtract angle B from 180 degree to find out the degree of the particular angle. Hope I helped.

Okay, all of these pairs add up to 1 or 100%, except for one pair. I'll convert them all to decimals, so all must add up to 1.

3/8 = 0.375
0.625 + 0.375 = 1

62% = 0.62
0.38 + 0.62 = 1

7/8 = 0.875
0.875 + 0.125 = 1

70% = 0.70
1/3 <span>≈</span> 0.33
0.70 + 0.33 = 1.03

So the last pair of probabilities(70%, 1/3) does not belong with the other three because it does not add up to 1 like the others.
