Answer:
Step-by-step explanation:
{4x + y = 3
{x + y - z = 9 ←
{2x + 2y + z = 0 ←
{4x + y = 3
{3x + 3y = 9 >> Combined equation
−¾[4x + y = 3]
{−3x - ¾y = −2¼ >> New Equation
{3x + 3y = 9
_________
2¼y = 6¾
___ ___
2¼ 2¼
[Plug this back into all three equations to get the z-value of −6, and the x-value of 0];

Answer:
The change in volume is estimated to be 17.20
Step-by-step explanation:
The linearization or linear approximation of a function is given by:
where
is the total differential of the function evaluated in the given point.
For the given function, the linearization is:
Taking inches and
inches and evaluating the partial derivatives we obtain:
substituting the values and taking and
inches we have:
Therefore the change in volume is estimated to be 17.20
