question 178

Multiple Choice

Provide an appropriate answer.
-Suppose that $w = x ^ { 2 } + y ^ { 2 } + 20 z + t$ and $x + 4 z + t = 8$ . Assuming that the independent variables are $x$ , $y$ , and $z$ , find $\frac { \partial w } { \partial x }$ .

• A) \(\frac { \partial w } { \partial x } = 2 x - 5\)
• B) \(\frac { \partial w } { \partial x } = 2 x + 5\)
• C) \(\frac { \partial w } { \partial x } = 2 x + 1\)
• D) \(\frac { \partial w } { \partial x } = 2 x - 1\)
