Answer:
S₉ = 255.5
Step-by-step explanation:
the sum to n terms of a geometric sequence is
= 
where a₁ is the first term and r the common ratio
here a₁ = 0.5 and r = 
= 
= 2 , then
S₉ = 
= 
= 0.5(511)
= 255.5
Answer:
They are equivalent
Step-by-step explanation:
2x+14 = 8
Lets solve for x
Subtract 14 from each side
2x+14-14 = 8-14
2x = -6
Divide by 2
2x/2 = -6/2
x = -3
They are the same

Answer:
–6x + 15 < 10 – 5x
An open circle is at 5 and a bold line starts at 5 and is pointing to the right.
Step-by-step explanation:
When you break down -6x + 15 < 10 - 5x, you get x > 5.
Because x is GREATER than 5, when making a number line, there is an open circle on 5 and a bold line pointing to the right.
