t is of interest to find the equations of the tangent to x^2+y^2=10 at (a,b) where the point is on the curve.
Taking the derivative, 2+2′=0⇒′=− , and so the slope of the tangents are =− .
The equation of the tangent looks like
=−+⇒=−2+⇒=2+2=10
The equation becomes, +=10 .
Now use this formula.
Answer:
A for me... hope this helps you
Answer:
lesser x = -2, greater x = 2/3
Step-by-step explanation:
(2x+4)= 0 ---> bring 4 to the other side
2x=-4 ----> divide by 2 on both sides
x= -4/2 = -2 ----> simplify
(3x-2)= 0 ----> bring the 2 to the other side
3x=2 ----> divide by three on both sides
x=2/3
hope this helps!
