If y = xy + x2 + 1, then when x=-1,
dy/dx
2 answers:
Answer:
The dy/dx (derivative) would be 2x + y.
Plugging in x = -1, the answer would be y - 2.
Step-by-step explanation:
I passed single-variable Calculus with a perfect 100.

PLEASE MARK AS BRAINLIEST!!!!!</em></u></h2>
Given y = xy + x^2 +1, first find y = f(x) = (x^2 + 1) / (1 - x). Then use the quotient rule for derivatives.
dy/dx = [( 1 - x)( 2x) - (x^2 + 1)(-1)] / (1 - x)^2. Substitute the value of x = -1 into the above derivative and get -1/2.

Answer:
x=26
Step-by-step explanation:
1/3(x-2)=1/5(x+4)+2
x-2=3/5x+42/5
5x-10=3x+42
5x-3x-10=42
5x-3=42+10
2x=42+10
2x=52
x=26
