Region 1:
Ordered pair -- (0, 50)
Explanation: The red region represents solutions to the red line inequality that are not solutions to the blue line.
Region 2:
Ordered pair -- (50, 0)
Explanation: The purple region represents solutions to both the red line and blue line.
Region 3:
Ordered pair -- (20, - 10)
Explanation: The blue region represents solutions to the blue line inequality that are not solutions to the red line.
Region 4:
Ordered pair -- (0, 0)
Explanation: The white region represents all points/ordered pairs that are not solutions to either inequality.
Answer:
The GCF is .
Step-by-step explanation:
The GCF is the greatest common factor between both terms.
Look at each term and its pieces, then compare.
- 3 and 8 have not common factors.
- and have a common factor of.
- and have as a common factor.
So
The GCF is .
Let X be the first and second number.
X+X = 18
+ X-X = 2
2X = 20 (divide both sides by 2
X = 10
Substitute the values to get the second number
10+X = 18
X = 18 -10
X = 8
Therefore, the numbers are 10 and 8
