What is the value of r of the geometric series

.8

Step-by-step explanation:

The r value of the geometric series is what we multiply by each time.

We are multiplying by .8 each time so that would be r

The correct option is 1.

Step-by-step explanation:

The given geometric series is

It means the nth term of the given geometric series is

          .... (1)

The nth term of an geometric series is

          .... (2)

where, a is first term and r is common ratio.

From (1) and (2), we get

The value of r is 0.8. Therefore the correct option is 1.

i really dont know

step-by-step explanation:

fa tha first one you gonna add y to both sides

it look like this

x-y+y=6+y

x=y+6

therefore your answer is

x =y+6

fa tha second one

you gonna flip tha equation

it gonna look like x-4y=y

then add 4 to both sides

it gonna look like tha

x-4 +4 =y +4

so therefore tha answer is x=y+4
