Hello!
The greatest common factor (GCF) is self explanatory. We find the factors of each number, and find the largest ones that are in common
12: 1,12,2,6,3,4
33:1,33,3,11,
As you can see, the greatest number these two have in common is 3.
Now for the next set.
45: 1,45,3,15,5,9
70:1,70,2,35,5,14,7,10
As you can see, our GCF is 5.
Therefore, our answers are below.
9) 3
10) 5
I hope this helps!
A printer shop purchases a new printer fro $25,000
the equipment depreciates at a rate of 5% each year
the relationship between the value of the printer, y, and the year number, x can represented by the equation y=25,000*0.95^x
year 1: $23,750
year 2: $22,562.50
year 3: $21,434.38
