(1/3) -y = (1 -3y)/3
There are many ways to write an equivalent expression. This is one of them.
(x-1)(x^3+x^2+x+7) is your answer.
Answer: The slope is 1/4.
Step-by-step explanation:
To find the slope, find two points on the line and find the difference in their y coordinates and divide it by the difference in their x coordinates .
(0,20) and (40,30)
Difference in y: 30 - 20 = 10
Difference in x: 40 - 0 = 40
Slope: 10/ 40 = 1/4
The corresponding answers for each student plan are:
plan A: 15 years
plan B: 5 years
plan C: 10 years
plan D: 9 years
Thus, first, the graph corresponding to each of the plans must be analyzed. The Y-axis corresponds to money and the x-axis corresponds to the time in years.
Thus, in-plane A, it can be observed that to reach the desired value, the graph will be projected in exponential, so it will be close to 15 years. In plan B, this projection will be reached around 5 years. In plans C and D, this projection will be 10 years and 9 years respectively.
