which graph best represents a decreasing function?

First graph

Step-by-step explanation:

The first graph is strictly decreasing because it starts from point (0;4) and decrease to point (4;0).

While graph 2 and 3 is constant

Since graph 2:y=2 and 3:x=1

And graph 4 is strictly increasing from (0;0) to (4;4).

the answer would be 1 1/72

step-by-step explanation:

you can rewrite the equation by separating the parts and then solving individually:

10-9=1

1/8 - 1/9=

find l c d and then combine:

1 1/72

c. side angle side. u shares the same sides
