Answer:
use circumfrence, look in your notes for the formula as the queastion states
Step-by-step explanation:
Answer:
y-6=4(x+1) or y=4x+10
Step-by-step explanation:
Point: (-1,6)
m=4
Slope-point form is y-y1=m(x-x1)
y1=6
x1=-1
Now, plug it in!
y-6=4(x-(-1)) which is y-6=4(x+1)
Of course, if you want you could always simplify it down to y=4x+10 if you wanted to
Hope this helps!
4x + 6 < -6
subtract 6 from each side
4x < -12
divide by 4
x < -3
- 2/5 x-9 < 9/10
multiply each side by 10 to get rid of the fractions
10*(- 2/5 x-9) < 10*9/10
distribute
-4x -90 <9
add 90 to each side
-4x < 99
divide by -4 (which flips the inequality)
x> -99/4
x> -24 3/4
The Lagrangian is

with critical points where the partial derivatives vanish.



Substitute
into the last equation and solve for
:

Then we get two critical points,

We get an absolute maximum of
at the second point, and an absolute minimum of
at the first point.
