Just graph the coordinates
this picture is the different quadrants on the graph, whichever quadrant the coordinate is in, is what you put in the 2nd column
for example: (-2,-3) is in the 3rd quadrant
if its not in a quadrant its either on x or y axis, so its just on the line, and i assume you know which axis is which

for number 4. You just do subtraction, and then if its negative, it becomes positive since its asking for the absolute value
for example: |-24-11| > |-35| > 35

Help please my teacher isn't the greatest.
Schach [20]

Answer:

x = 9.5

Step-by-step explanation:

We see that the entire length of DF is equal to 34. That means segment DE and segment EF must combine to equal 34:

3x - 6 + x + 2 = 34

4x - 6 + 2 = 34

4x - 4 = 34

4x = 38

x = 9.5
