Answer:
29
Step-by-step explanation:
at 9 on both sides to get m alone
-9+m=20
+9. +9
m= 29
Y/x = 5 bc in order to isolate the variables you must divide by x on both sides to separate the 5, leaving you with y/x=5
The
first graph.
The equation is x - 1

3
In order to solve it, you need to get x by itself.
Add 1 to both sides. 3+1=4
x

4
Since this is your sign

the arrow has to point towards the left, and the circle needs to be colored in.
