8x+6+4= 3x- 2x- 4 is the correct step
The solution for the #23 equation is either x=9 or x= -3
Answer: 
Step-by-step explanation:
Given: The first term of Geometric series : a=1
The seconds term of Geometric series : 
The common ratio between the terms is given by :-

We know that the sum of infinite geometric series is given by :-

Hence, the sum of the given infinite series = 
Answer:
x=-3,x=9
Step-by-step explanation:
x^2-6x-20-7=0
x^2-6x-27=0
x^2-(9-3)x-27=0
x^2-9x+3x-27=0
x(x-9)+3(x-9)=0
(x+3)(x-9)=0
x=-3,x=9
Just remember that 100% = 1.00 !
y = .78x
y = 108.5x
y = .946x
