Answer:
im pretty sure 9 is 100.9(growing) or 0.95 (pop shrinking) and 13 is 0.8566
Step-by-step explanation:
So the slope is (y2-y1)/(x2-x1)
(8-4)/(2-1)=
4/1 =
4
Aka. For every 1 week, the number of pictures taken increases by 4.
So it is 4 * w
Check:
4*w = total number of pictures
4*1 = 4
4*2 = 8
4*3 = 12
4*4 = 16
All match the table.
Answer:
2/3
Step-by-step explanation:
Slope = 
(-4,2) = (x1,y1)
(-16,-6) = (x2,y2)
Slope = 
= 
= 
Answer:
Youngest: 13 years old
Middle: 18 years old
Oldest: 26 years old
Step-by-step explanation:
2c + c+5 + c = 57
4c = 52
c = 13 years (youngest)
a = 2c = 26 years (oldest
b = c+5 = 18 years (middle)
