Answer:
x = 11/5
____________________________________________________
Step-by-step explanation:
We are solving for x:
3(4 – 2x) = -x + 1
Distribute the 3 to the 4 and -2x
12 - 6x = -x + 1
Add x to both sides to get the x's together
12 - 5x = 1
Subtract both sides by 12
-5x = -11
Divide by -5. Two negatives turn into a positive.
x = 11/5

Answer:
Slope of a tangent to the curve =
Step-by-step explanation:
Given - y = 1/x+1
To find - Identify each expression that represents the slope of a tangent to the curve y=1/x+1 at any point (x,y) .
Proof -
We know that,
Slope of tangent line = f'(x) =
We have,
f(x) = y =
So,
f(x+h) =
Now,
Slope = f'(x)
And
∴ we get
Slope of a tangent to the curve =
