In the first octant, we assume

, so we can ignore the caveats above. Now,

so that the only critical point in the region of interest is (1, 2, 2), for which we get a maximum value of

.
We also need to check the boundary of the region, i.e. the intersection of

with the three coordinate axes. But in each case, we would end up setting at least one of the variables to 0, which would force

, so the point we found is the only extremum.
Answer:
(3 * 3^2)+(2 * 4^2)
combined area is 59 sq ft
3t = 5t - 8
-2t = -8
t = 4
Now put that into -4t + 5:
-4t + 5
-4(4) + 5
-16 + 5
-11

Answer:
The equation in the slope-intercept form will be:
Step-by-step explanation:
Given the points
Finding the slope between the points using the formula




We know that the point-slope of the line equation is

substituting
and (-39,49) in the equation


Now writing the equation in slope-intercept form

where m is the slope and b is the y-intercept






∵ 
Where
and the y-intercept i.e. 
Therefore, the equation in the slope-intercept form will be:
