Answer:
The slopes of OA, OB ans OC are integer values.
Step-by-step explanation:
If a line passing through two points then the slope of the line is

If one point is origin then the slope of the line is

The slope of line OA is

It is an integer.
The slope of line OB is

It is an integer.
The slope of line OC is

It is an integer.
The slope of line OD is

It is not an integer.
The slope of line OE is

It is not an integer.
The slope of line OF is

It is not an integer.
Therefore the slopes of OA, OB ans OC are integer values.
Answer:240 square centimeters
Step-by-step explanation:
1. 10x7=70
2. 7x10=70
3. 25x4=100
70+70+100=240
Because 12% of the staplers were defective or considered defective, we simply find 12% of a number that is equvalent to 90:
0.12x = 90
x = 750
750 staplers were produced
