Answer:
d is wrong

Answer: 
Step-by-step explanation:
This is a <em>homogeneous linear third-order differential equation</em>
z′′′+2z′′−4z′−8z=0 so the
FIRST STEP is to find the characteristic equation and its roots
<em>
</em>
Using the method of finding roots of a polynomial (using m = 2) would provide the solution below
(m-2)(m+2)(m+2)=0; m = 2 and m = -2 (repeated twice)
SECOND STEP is to write the general solution with the arbitrary constants.
The general solution based on the roots and the using x as the independent variable would provide
<em>*It should be noted that when the characteristic equation has a repeated root, the general equation form becomes similar to the last part of the answer*</em>
Answer:
7/3
Explanation:
The slope of the line is equal to the rise/run, or in other words, the number of units the line travels upwards over the number of units the line travels to the right.
We can identify the slope using any two points on the line. Here, we can use the two points that are marked on the picture. The second point is 7 units above the first and 3 units to the right of the first, so the slope of the line is equal to 7/3.
Another way to calculate the slope of the line is the use this formula:
(y2-y1)/(x2-x1)
The first point is at the coordinate (1,-4) and second point is at the coordinate (4,3). When we plug these two coordinates into the equation, we get this:
(y2-y1)/(x2-x1)
->(3-(-4))/(4-1)
When we simply the fraction, we would get 7/3 and that would give us the slope.
