Answer:
The mapping can also be represented as the set of ordered pairs: (4, 9) (5, 10) (6, 11) (7, 12). The ordered pair preserves the directional property of the relation. It is consistent with the order of points plotted on a Cartesian Plane represented by (",$). In the Arrow Diagram that follows.
Step-by-step explanation:
2/10 x 2/10 = 4/10 that can be a expression sorry if im wrong
A=b-2
c=d/3
e=2f+5
hope this helps
Edited in the comment ............
Isolate x; you must get all the constants on one side of the equation and the variables on the other side. Use subtraction/addition to do this. Reply to me once you've done that if you still need help.
