PLEASE HELP, IT WOULD BE MUCH APPRECIATED!! THANK YOU SO MUCH!! Do the graphs above show a relation, a function, both a relation
rewona [7]

Answer:

Well it definitely can't be a function

Step-by-step explanation:

To find out if a graph is a function, you can use the vertical line test. The vertical line test is when you draw a line down the center and if it hits one point, it's a function. But, when it hits more than one point, it's not. In this case, a line would hit more than one point; meaning that they are not functions.

GREYUIT [131]
The answer is D. First, it is the segment addition postulate because the two segments make up the whole. Second, it's substitution because you are substituting EF + FG for FH.

Hope this helps!

Use common denominators to determine whether the ratios form a proportion.
AURORKA [14]
They are not in proportion, since its 6:9 round it down (2:3) so pretend the 6 are apples and the 9 are oranges

Every 2 apples there are 3 oranges

So having 9 apples what is that?

2 x ? = 9

2 x 4.5 = 9

So if you want to keep 2:3 you have you times the oranges by 4.5 aswell!

3 x 4.5 = 13.5

So since it is 9:12 not 9:13.5 they are not in proportion
