1) 3^3 * 4^3 = 12^3
2) 3^4 * 3^3 = 3^7
3) 3^4 * 4^3 = 12^12
They are all equal.
Answer:
You would need $18 total to buy the racks needed.
Step-by-step explanation:
First, every 20 CDs needs a new rack, so you would divide 120 by 20.
120 / 20 = 6 racks
Second, you would multiply the price ($3) of a rack by how many racks needed.
3 * 6 = $18
The average rate of change in the median household income over this time period is $745.5
<h3>What is the average rate of change in the median household income over this time period?</h3>
The given parameters are:
2000, the median household income was $41,990.
2010, it was $49,445.
The average rate of change in the median household income over this time period is calculated as:
Average rate of change = (Difference in Income)/(Difference in years)
So, we have:
Average rate of change = (41990 - 49445)/(2000-2010)
Evaluate
Average rate of change = 745.5
Hence, the average rate of change in the median household income over this time period is $745.5

Answer:
a) v = 0
b) b = 7 / 6
c) a = any number
Step-by-step explanation:
a) 7(2+5v)=3v+14
7 x 2 + 7 x 5v = 3v + 14 .... distributive
14 + 35v = 3v + 14
35v - 3v = 14 - 14
32v = 0
v = 0 ...... only v value can fit
b) -3 (3-6b)=6b+5
-9 + 18b = 6b + 5
18b - 6b = 5 + 9
12b = 14
b = 14 / 12 = 7 / 6
c) 2 (a-2)=2a-4
2a - 4 = 2a - 4
2a -4 + 4 = 2a -4 + 4
2a = 2a
a = a ........ a cab be any number
