Answer:
6(x-3)(X^2+4)(x+1)=0
real answers:
(x-3)=0
x=3
x+1=0
x=-1
This numbers are not real:
x^2+4=0
x^2=-4
= ±
To solve this, you must subtract .56 from -1.64. Then divide that by -5.5x. So the answer is .4
When we write a line equation in the form

m is the slope of the line, and q is the y-intercept.
Since we want the y-intercept to be -3, our line will look like

In order to fix the slope, remember that two parallel lines have the same slope. So, the slope of the given line y=2x-5 is 2, and since we want a line parallel to this line, our slope will be 2 as well.
Plugging the values, we can finish the equation:

Answer:
Average rate of change: 0
Interpretation: No increment in yield from year 5 to year 15.
Step-by-step explanation:
The function that models the yield is:



The average rate of change of f(x) from x=a to x=b is given by the formula;

The average rate of change from year 5 to year 15 is:



Interpretation: There has not been any increment in yield from year 5 to year 15.
