I'm pretty sure that it would be -92.
Answer:
1. |r| = 1/4. or 0.25
2. Since r < 1, the geometric series is convergent.
3. To obtain the sum, we consider the formula of obtaining the sum to infinity of a geometrical series;
S = a /(1 - r)
where a = 2 ( first term)
r = 0.25 ( common ratio)
Therefore:
S = 2 /( 1 - 0.25)
= 2 / 0.75
= 8/3 or 2.6667
Hence, the sum is 8/3
Answer:
y = 3x - 5
Step-by-step explanation:
I used my calculator so that it would be faster.
But if you want work you have to find the slope then plug in.
To find the slope use points (1, -2) and (2, 1) use this formula
Plug the points in
So your slope is 3
NOw Plug In (1, -2)
-2 = 3(1) + b (b represents the y- intercept)
-2 = 3 + b (subtract 3 on both sides)
-5 = b
The final equation is y = 3x - 5
Hope this helps ya!!
