Answer:
6(xy-4)
6x+5
Step-by-step explanation:
Coefficient is number before variable



There is one critical point at (2, 4), but this point happens to fall on one of the boundaries of the region. We'll get to that point in a moment.
Along the boundary
, we have

which attains a maximum value of

Along
, we have

which attains a maximum of

Along
, we have

which attains a maximum of

So over the given region, the absolute maximum of
is 1578 at (2, 44).
<span>4x(5y-x)-5y(4x-y)=20xy-4x^2-20yx+5y^2=-4x^2+5y^2=5y^2-4x^2</span>
Y=mx+b, m=slope, b=y intercept
a line that is paralell will have the same slope with a different y intercept
y=4x-10
therefor the new equation is y=4x+b
subsitute
(x,y)
(5,-6)
x=5
y=-6
is on e solution so subsitue
-6=4(5)+b
-6=20+b
subtract 20
-26=b
the equation si y=4x-26
Answer:
2x^2=-8
2x^2/2=-8/2
x^2=-4
x=2
Step-by-step explanation:
HOPE THAT THIS IS HELPFUL.
HAVE AN AWESOME DAY.
