What is the final elevation if a butterfly starts at 20 m and changes negative 16 m

iVinArrow [24]

Answer:

4 meters

Step-by-step explanation:

Given that :

Initial elevation of butterfly = 20 meter

Change in elevation from initial height = negative 16 m = - 16 meter

Final elevation can be obtained by taking the sum of initial elevation and the change in elevation

(20 m + (- 16 m))

(20 m - 16 m)

= 4 meters

Determine the value(s) of h such that the matrix is the augmented matrix of a consistent linear system. [Start 2 By 3 Matrix 1s

Leni [432]

Answer: h = 9

Step-by-step explanation: A system of linear equations is consistent when it has at least one solution.

The matrix given is:

$\left[\begin{array}{ccc}-15&21&h\\5&-7&-3\end{array}\right]$

Transform this matrix in a row-echelon form:

$\left[\begin{array}{ccc}-15&21&h\\5&-7&-3\end{array}\right]$ $R_{2} = 3R_{2}+R_{1}$ $\left[\begin{array}{ccc}-15&21&h\\0&0&-9+h\end{array}\right]$

For this row-echelon form to have solutions:

-9 + h = 0

h = 9

For this system to be consistent: h = 9.
