<h2>Common ratio = -1/2</h2>
Step-by-step explanation:
term of a Geometric progression is given as 
. The first term is given as 
.
Any general Geometric progression can be represented using the series 
.
The first term in such a GP is given by 
, common ratio by 
, and the 
term is given by 
.
In the given GP, 
∴ Common ratio is 
.
Step-by-step explanation:
the answer is
the Value of b to 2
Answer:
7/9y+441/567
Step-by-step explanation:
y^2-49/81y+567÷y-7/63
=y^2-49/81y+567×63/y-7
=(y-7)(y+7)/81y+567×63/y-7
=(y+7)×63/81y+567
=63y+441/81y+567
=7/9y+441/567
Using substitution and graphing, I found that x=0.833 and y=1.6
(0.833, 1.6)
