On a coordinate plane, a straight line and a parallelogram are shown. The straight line has a negative slope and has a formula o
f y = negative x. The parallelogram has points G (negative 2, negative 3), F (1, negative 3), E (negative 1, negative 5), and H (2, negative 5).

y = –x?
A. (–1, –3)
B. (3, –1)
C. (1, 3)
D. (–3, 1)

Answer:
7.2224
Step-by-step explanation:
The value of the summation is given by the formula ...
Sn = (a1)(1 -r^n)/(1 -r) . . . . . where a1 is the first of n terms, and r is the common ratio.
Your sum has first term and ratio ...
a1 = 2(0.6) . . . . . summation term for n=1
r = 0.6
So the sum is ...
Then the value of the entire given expression is ...
