Answer:
C. 16
Step-by-step explanation:
5 is half of 10, so 8 should be half of the next number.
3x + 3y = 27
3x - 3y = -11
------------------add
6x = 16
x = 16/6 which reduces to 8/3
3x + 3y = 27
3(8/3) + 3y = 27
8 + 3y = 27
3y = 27 - 8
3y = 19
y = 19/3
solution is (8/3, 19/3)
If A=38x-x^2 then
dA/dx=38-2x
d2A/dx2=-2
Since the acceleration, d2A/dx2 is a constant negative, when velocity, dA/dx=0, it will be an absolute maximum for A(x)
dA/dx=0 only when 38=2x, x=19
A(19)=38(19)-19^2
A(19)=722-361
A(19)=361 ft^2
So the maximum possible area is 361 ft^2
(This will always be true as the maximum possible area enclosed by a given amount of material will always be a perfect square...)
Answer:
y + 8 = 1/2(x + 3)
