2 answers:

7 0

$r = \frac{-14}{2} \\
r = -7\\ \\
a_{n} = a _{1} * r^{n-1}\\ 
a_{6} = 2 * (7)^{7-1}\\
a_{6} = 2 * -7^{6}\\
a_{6} = 2 * -117649 \\
a_{6} = -235298 \\ 
\\ letter "D"

Solve the system

Alexxandr [17]

Answer:

x = $\frac{2u+v}{7}$

y = $\frac{2v - 3u }{7}$

Jacobian value = 1/7

Step-by-step explanation:

Given data:

u = 2x -y

v = 3x + 2y

solving the system for x and y in terms of u and v

x = $\frac{2u+v}{7}$

y = $\frac{2v - 3u }{7}$

The value of the Jacobian = 1/7 ( solution attached below )

Image under the transformation of the triangular region with vertices ( 0,0) , (2,4) and (2,-3) in the x-y plane is attached below
