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 )

Ian factored 12x3y3 – 24x2y3 into 6xy(2x2y2 – 4xy2).
jonny [76]
A. 6xy(2x^2y^2-4xy^2) If you need to multiply 6xy and 2x^2y^2 & 6xy and 4xy^2. You will get 12x^3y^3-24x^2y^3. b. Factorization is not complete because 6xy is not the greatest common factor. c. Complete factor: 12x^2y^3(x-2y).

12. Find a number t such that the line containing the points
yKpoI14uk [10]

Answer:

t= 11

Step-by-step explanation:

\boxed{gradient =  \frac{y1 - y2}{x1 - x2} }

Gradient of line that contains points (3, 7) & (5, 11)

=  \frac{11 - 7}{5 - 3}

=  \frac{4}{2}

= 2

The product of the gradients of two perpendicular lines is -1.

Gradient of the line that contains points (t, -2) & (-3, 5)

= -1 ÷2

=  -  \frac{1}{2}

\frac{ - 2 - 5}{t - ( -3 )}  =  -  \frac{1}{2}

\frac{ - 7}{t + 3}  =   \frac{ - 1}{2}

Cross multiply:

-(t +3)= -7(2)

Dividing by -1 on both sides:

t +3= 7(2)

t +3= 14

t= 14 -3

t= 11
