Answer:
Sum of the sequence (Sn) = 33,859
Step-by-step explanation:
Given:
Sequence = 685+678+671+664+...+6
Find:
Sum of the sequence (Sn)
Computation:
a = 685
d = 678 - 985 = -7
an = 6
an = a+(n-1)d
6 = 685+(n-1)(-7)
-679 = (n-1)(-7)
97 = n-1
n = 98
So,
Sum of the sequence (Sn) = (n/2)[a+an]
Sum of the sequence (Sn) = (98/2)[685+6]
Sum of the sequence (Sn) = (49)(691)
Sum of the sequence (Sn) = 33,859
Answer:
9
Step-by-step explanation:
8-6(2)/4+2(2)
8-12/4+4
8-3+4
9 not sure though
Y=-2/3x-2
Slope:-2/3
Slope intercept form is y=mx+b. So you have to isolate the y.
Subtract 2x from both sides
3y=-2x-6
Divide 3 from both sides
y=-2/3x-2
The answer would most likely be the first, second, and the third option.
