Answer:
Answer:
3x + 3y = 0
7x - y = 8
Step-by-step explanation:
The equation has one solution, x = 0
3x = 4x
-3x both sides
0 = 4x - 3x
0 = x
Answer:
y = 9x + (-7) should be the answer
Given:
square shape
Perimeter 28 feet
Find its area
A square has 4 equal sides, so perimeter is 4a
Perimeter = 4a
28 ft = 4 a
28 ft / 4 = a
7 = a
One side of the the square is 7 ft.
Area of a square is the measure of one side raised to the power of 2.
A = a²
A = (7 ft)²
A = 49 ft²
If

then the derivative is

Critical points occur where
. This happens for



In the first case, we find

In the second,

So all the critical points occur at multiples of
, or
. (This includes all the even multiples of
.)
