Answer:

y= 13/22

Step-by-step explanation:

x=4-6y

equation: 4x + 2y=3

4(4-6y) +2y = 3

use distributive property

16 - 24y + 2y = 3

Combine and collect like terms:

16 -22y = 3

-22y = 3 - 16

-22y = -13

y= -13/-22

y= 13/22

Hope this helps :)

Answer:

4(4-6y) + 2y = 3

Step-by-step explanation: Just substitute x into 4-6y multiplied by 4 since x is by itself in the second equation.

Answer:

The maximum variance is 250.

Step-by-step explanation:

Consider the provided function.

$V(x)=1000x(1-x)$

$V(x)=1000x-1000x^2$

Differentiate the above function as shown:

$V'(x)=1000-2000x$

The double derivative of the provided function is:

$V''(x)=-2000$

To find maximum variance set first derivative equal to 0.

$1000-2000x=0$

$x=\frac{1}{2}$

The double derivative of the function at $x=\frac{1}{2}$ is less than 0.

Therefore, $x=\frac{1}{2}$ is a point of maximum.

Thus the maximum variance is:

$V(x)=1000(\frac{1}{2})-1000{\frac{1}{2}}^2$

$V(x)=250$

Hence, the maximum variance is 250.
