Answer:
Step-by-step explanation:
Created Sequences
S1: 10 20 40 80 150
s2:24 20
The first term that appears in both sequences is the second term. Both of them equal 20.
I don't think you have to go any further once you get the first term.
Method
S1: Multiply by 2 starting with 10.
10*2 = 20
20*2 = 40
S2: Start at 24 and subtract 4
24 - 4 = 20
20 - 4 = 16
16 - 4 = 12
The domain is R so the first one is correct.
Step-by-step explanation:
You just have to plug the numbers they give you into the equation. For the first one, you have 0 + 5y = 10; 5y = 10; y = 2. For the second one, x + 5(0) = 10; x + 0 = 10; x = 10. And lastly, for the third one, x + 5(6) = 10; x + 30 = 10; x = -20.
Month*
divide 840 with 12
as 1 year has 12 months
and you get 70$
so the family spends $70 every month
