2(a - b) - (b - a) = 2a - 2b - b + a = 3a - 3b
Answer:
Rate Of Change= 7
Step-by-step explanation:
all you have to do is see the difference, imma make a table here first
x y
1 10
3 24
6 45
11 80
15 108
from 10 to 24 you add 14
from 1 to 3 you add 2
so y/x
14/ 2 = 7
check:
from 24 to 45 you add 21
from 3 to 6 you add 3
so y/x
21/3 = 7
From y/x your final answer will always be 7.
So the rate of change will be 7.
Hope this helped a little!

Answer:
The smaller number: a = 10
The larger number is 32
Step-by-step explanation:
a - the smaller number
2a - twice the smaller number
2a+12 - twelve more than the twice smaller number (the larger number)
a + 2a+12 - the sum of the numbers
a + 2a+12 = 42
-12 -12
3a = 30
÷3 ÷3
a = 10
2a+12 = 2×10+12 = 20+12 = 32
Check: 10+32=42
