The sum formula for a geometric sequaence is:

sum(n) = a1(1-r^n)/1-r

Where n is the number of terms, a1 is the first term and r is the common ratio:

s(8) = 3(1-1/2^8) / (1-1/2)

s(8) = 3(1-1/256) / 1/2

s(8) = 2 253/256 / 1/2

s(8) = 765/128

The answer is C.

\quad \huge \quad \quad \boxed{ \tt \:Answer }

\qquad \tt \rightarrow \:2x - 3

____________________________________

\large \tt Solution  \: :

\qquad \tt \rightarrow \: (f - g)(x)

\qquad \tt \rightarrow \: f(x) - g(x)

Simple procedure :

\qquad \tt \rightarrow \: 3x - 1 - (x + 2)

\qquad \tt \rightarrow \: 3x - 1 - x - 2

\qquad \tt \rightarrow \: 3x - x - 1 - 2

\qquad \tt \rightarrow \: 2x -  3

Use the Line Tool to graph the equation. 2x−7y=14
kirza4 [7]

Convert to Y=MX+B to make it easier, minus 2x from both sides to get -7y=-2x+14, then divide it all by -7 to get y=2/7x-2. 2 equals your starting point, from there go down 2 and over 7 for you slope and repeat until the graph is done.
