Answer:
x(7+15)
-19
Step-by-step explanation:
Answer:
x= -1
Step-by-step explanation:
First add 2x to the 7x it will look like this
9=9x
Now you need x by itself so divide 9 on both sides it will look like this
1=x and thats your answer just swap the x and the 1
The curve

is parameterized by

so in the line integral, we have





You are mistaken in thinking that the gradient theorem applies here. Recall that for a scalar function

, we have gradient

. The theorem itself then says that the line integral of

along a curve

parameterized by

, where

, is given by

Specifically, in order for this theorem to even be considered in the first place, we would need to be integrating with respect to a vector field.
But this isn't the case: we're integrating

, a scalar function.
