Answer:
- 3 1/4
- 10.6
- 3 1/3
Step-by-step explanation:
- <em>The distance = number to the right - number to the left</em>
1..................................................................
- -2 1/2 - (-5 3/4) = -5/2 + 23/4 = - 10/4 + 23/4 = 13/4 = 3 1/4
2...................................................................
- 8.4 - (-2.2) = 8.4 + 2.2 = 10.6
3...................................................................
- -3 2/3 - (- 7) = -11/3 + 7 = - 11/3 + 21/3 = 10/3 = 3 1/3
Answer:
Step-by-step explanation:
The y-intercept is super easy. The y-intercept exists when x = 0; therefore, the point given where x = 0 is found in (0, -15). That means that the y-intercept is -15. Easy enough. Now, the slope.
Since all these points are on the same line, using any 2 of them in the slope formula will get us the slope. I picked the first 2 points (1, -19) and (-4, 1):
The y-intercept is -15 and the slope is -4
We''ll use $100 and $200 for the investment amounts.
Using the attached formula,
Years = natural log (200 / 100) / .12
Years = natural log (200 / 100) / .12
Years = 0.69314718056 / .12
