Determine whether the following series is arithmetic or geometric. Then evaluate the finite series for the specified number of terms.
81 + 27 +9+3+...; n= 180
Choose the correct answer below.
The series is arithmetic.
The series is geometric.
The sum is S180 =
(Type an integer or decimal rounded to two decimal places as needed.)

answer:

given the linear inequality :

add 2y to both sides we get;

simplify:

add 12 to both sides of an equation;

simplify:

divide both sides by 2 we get;

or

the related equation for the inequality equation [1] is;

y-intercepts defined as the graph crosses the y-axis.

substitute x =0 in [2] to solve for y;

y = 6

x-intercepts defined as the graph crosses the x-axis.

substitute value y = 0 to solve for x;

subtract 6 from both sides we get

multiply both sides by 2 we get;

or

x = -12

now, plot these point (0, 6) and (-12, 0) on graph as shown below and shade the graph below the solid line.
