Answer:
Step-by-step explanation:
GIVEN: A fence is to be built to enclose a rectangular area of square feet. The fence along three sides is to be made of material that costs dollars per foot, and the material for the fourth side costs dollars per foot.
TO FIND: Find the dimensions of the enclosure that is most economical to construct.
SOLUTION:
Area of rectangular fence
let the length of fence
let the width of fence
let be the smaller side
Area of rectangular fence enclosure
cost of fence along three sides
cost of fence along fourth side
length of fence
cost of fence building
putting value of
to find minimum value differentiating the equation
Hence the dimensions of the enclosure that is most economical to construct are and
72/8 = 9
“/“ means division by the way.

A few simple calculations gives these answers. reply to this if you want work shown.
Answer:
<u>y = -1 (x) -1</u>
Step-by-step explanation:
If you plug in the numbers from the coordinates into the equation, you will find that it's true.
-1 is x and 0 is y. Plug in the #s like so:
y = -1 (x) -1
0 = -1 (-1) - 1
0 = 1 - 1
0 = 0
Therefore, the equation above represents the line that passes through both these points.
