Answer:
the equation for the line would be y=-1/3x
Answer:
2 5/8 inches
Step-by-step explanation:
This is a subtraction problem.
You must subtract 58 1/8 inches from 60 3/4 inches.
We need a common denominator for the fractions.
The LCD of 4 and 8 is 8.
60 3/4 = 60 6/8
58 1/8 = 58 1/8
60 3/4 - 58 1/8 = 60 6/8 - 58 1/8 = 2 5/8
Answer: 2 5/8 inches
Answer:
y>-8
Step-by-step explanation:
The minimum range is found at the lowest point on the graph, which in this case, is -8. The point is not filled in, so -8 is not included in the range.

The answer to this question:
<span>north and south sides 16ft
east and west sides 8ft
</span>
In this question, the east and west fencing cost is $4/ft but the south and north fencing cost is $2/ft. The cost is cheaper for fencing north and south side which cost half of the east and west side. The perimeter is made by adding the south, north, east and west side.
If x = north and south fencing and y= is east and west side, then you can get this equation
cost= (south+north) * $2 + (east+west)*$4
128=(x+x) * 2 + (y+ y) * 4
128= 4x + 8y
32= x+ 2y
x= 32-2y
The area is count by multiplying the width and length, which was x and y in this question. The formula should be:
area= length * width
area= x * y
area= (32-2y) * y
area= 32y - 2y^2
Then, you need to find the value of y needed for the maximum area.
32y- 2y^2
32 - 2*2y=0
32= 4y
y= 8
If y=8 then
x= 32-2y
x= 32- 16= 16
