Step-by-step explanation:
The slope of tangent line at a max or a minimum is 0,.
So using point slope formula.


Is the equation of a tangent line. This means we have a horizontal line at y= 4. Horizontal lines have a slope of 0.
Answer:
3b+b and 2(2b)
Step-by-step explanation:
C; On this line, any two values have to add to 2.
-9=6/v
You have to multiply v both sides because
6/v x v = 6 and helps you get rid of the v on the right side.
If you multiply by 6, 6/v x 6 = 36/v, that’s why it don’t work.
Answer:
-9=6/v
-9v=6
v=-6/9
v=-2/3
