Answer:
C
Step-by-step explanation:
The sum to n terms of a geometric sequence is
=
Here a₁ = 4 and r = - 3, thus
=
= = - (729 - 1) = - 728 → C
3x + 4y = - 8
The equation of a line in standard form is Ax + By = C
where A is a positive integer and B, C are integers
Express the line in ' slope- intercept form '
y = mx + c → (m is the slope and c is the y-intercept)
here m = - and c = - 2
hence y = - x - 2 → equation in slope- intercept form
multiply all terms by 4
4y = - 3x - 8
add 3x to both sides
3x + 4y = - 8 → in standard form
