Answer:
The rate of return is 14%
Step-by-step explanation:
The rate of return can be determined by,
RR = x 100%
where:
RR is the rate of return
is the final amount = $690 - $6 = $684
is the initial amount = $15 x 40 = $ 600
So that,
RR = x 100%
= 0.14 x 100%
= 14%
Therefore, the rate of return is 14%.
Answer:
Step-by-step explanation:
1. The slope-intercept form of a linear equation is , where y = y-coordinate, m = slope, x = x-coordinate, and b = slope.
2. To find the slope, let's take the two points (0,0) and (-40,10). After that, let's plug in the values to their corresponding variable in the formula:
3. Since we now know our slope, the equation looks like this so far: .
4. Because b is the y-intercept, b = 0 because the line intersects the y-axis at (0,0).
5. Now that we have the values of m and b, we plug in them to get the equation of:
