$189/$21 =9 hours
The odd-numbered terms are

, while the even-numbered terms are

, so one formula for the sequence is

where

Answer:
A={5,1,-7}
Step-by-step explanation:
domain = x
choose domain {-2,0,4} to 2x+y=1
range = y
range is
2(-2)+y =1 ,y =5
2(0)+y=1, y= 1
2(4)+ y=1, y=-7
range = {5,1,-7}
Answer:
:))
Step-by-step explanation:
Collect like terms, keeping the integer rules in mind
5. 5a + 9b - 3a + 2b + 4a
5a + 4a - 3a + 9b + 2b (REARRANGE, if you find it to help)
6a + 11b
6. 7m + 3n - 8m + 2n + 10m
7m + 10m - 8m + 3n + 2n
9m + 5n
10. 10m²n + 5mn + 9m²n - 2mn
10m²n + 9m²n + 5mn - 2mn
19m²n + 3mn
Try to do the rest on your own :)
Yes. When you multiply a decimal number by 10, the decimal point moves one point to the right. Example:
0.05*10 = 0.5
This means that 0.003*10=0.03 since the decimal point moved one place to the right.
