|2x+3|-1<4
|2x+3|<5
1) when 2x +3 is positive
2x+3<5
2x<2
x<1 (-∞, 1)
2) when 2x+3 is negative
-(2x+3)<5
-2x-3<5
-2x<8
x>-4 (-4, ∞)
(-∞, 1)∩(-4, ∞)=(-4,1)
This is a geometric sequence since there is a common ratio between each term. In this case, multiplying the previous term in the sequence by 2 gives the next term.
I x i x i x i x i x i x i x i x i x i x i x i x i x i x i
Answer:
upper:65 lower:44
Step-by-step explanation:
1) start with (x-h)^2 + (y-k)^2 = r^2. Insert the given info: center at (-1,8) and radius 5:
(x+1)^2 + (y-8)^2 = 5^2 (answer)
