Answer:
129/8
Step-by-step explanation:
hope this helps!!!
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.

Step-by-step explanation:
So... errr... brainly doesn't allow cheating but i want to help so... here:
10^(-n)= 1/(10^n) following this, 10^-3=1/10^3 = 1/1000 = the second option (0.001)
Answer:
x = 
Step-by-step explanation:
(x + 6 )^2 = 49
get rid of the square , by square rooting the 49
x + 6 = 
x = -6
x =
means + or - hence it could be -7 -6 = -1 ... or 7-6 = 1
therefore the answer is = or - 1
hence in terms of roots .. answer is :
Your correct answer is option B
