Answer:
Length =
Breadth =
Step-by-step explanation:
Let be the length of the garden
and be the width of the garden
From the details of the cost in the question we get
Now area of the garden is
Differentiating with respect to x we get
Equating with 0
Double derivative of the area is
So, area is maximum at
So, the length and breadth of the rectangle is .
Answer: y = 3x - 4 will be the parallel line to the line y= 3x -1
Step-by-step explanation:
Parallel lines have the same slope but different y intercepts, so using the equation given , use the formula y=mx +b where m is the slope and b is the
y - intercept ,and input the x and y coordinate to solve for b. Input the same slope into the formula because they will have the same slope.
5= 3(3) + b
5 = 9 + b
-9 -9
b = -4
Since the y intercept is negative 4, the equation will be y = 3x -4

Answer:
x > −4
Step-by-step explanation:
Step 1: Add 5 to both sides.
6x-5+5 > -29+5
6x>-24
Step 2: Divide both sides by 6
6x/6 > -24/6
x > -4
