2 answers:

8 0

1. Subtract 2x from both sides
-y=6-2x

2. Multiply both sides by -1
y=-6+2x

3. Regroup terms
y=2x-6

4. Your answer, and my wish of you having a good day :D
y=2x-6

Y=1/2X-3, simplified of course.

Identify the sequence as arithmetic, geometric, or neither. Explain your answer.

This sequence (1.6, 0.8, 0.4, 0.2,... ) is geometric.
We have formula for any member of geometric sequence: $a_{n} = a_{1}* q^{n-1}$ If a1=1.6 then: $0.8=1.6*q, 0.4=1.6* q^{2}, 0.2=1.6* q^{3}$ The solution for all these equations is: q=0.5. We have: a1=1.6, q=0.5 and this is geometric sequence.
