1. order pairs : (3,1), (-2,-1)
1 + 1 / 3 + 2 = 2 / 5 is the slope
2. order pairs : (2,-3), (-3,2)
-3 - 2 / 2 + 3 = - 5 / 2 is the slope
3. order pairs : (1,3), (-1,-2)
3 + 2 / 1 + 1 = 5 / 2 is the slope
I used the slope formula to get my answers.
Answer:
The numbers are 2, 4, 6 and 8
Step-by-step explanation:
let the four numbers be x, y, z and l respectively
then:
x+y+z+l
(z+l)–6=4x
since they are all four consecutive even integers
then y=x+2
z=y+2=x+4
l=z+2=x+6
since (z+l)–6=4x
then ((x+4)+(x+6))–6=4x
2x+4=4x
4=4x–2x
4=2x
2=x
There are 4 common factors of 30 and 72, that are 1, 2, 3, and 6. Therefore, the greatest common factor of 30 and 72 is 6.
84/18=14/3
60/32=15/8
