The cost of fabric (y) is directly proportional to he length is yards (x). If 5 yards of fabric cost $14, which equation models
2 answers:
Answer:
Step-by-step explanation:
By definition, we know that Direct proportion equation has the following form:
Where <em>k </em>is the constant of proportionality.
Then, If 5 yards of fabric cost $14, you can calculate <em>k</em> as following:
Therefore substituting the value of <em>k</em> into the first equation, you obtain the following equation:

<u>Answer:</u> The perimeter is about 20.26 units
<u>Step-by-step explanation:</u>
To calculate the distance between the points, we use the formula:
where,
d = distance
are the coordinates of the points on x-axis
are the coordinates of the points on y-axis
For the given points:
B(0,3), C(4,-1), E(2,-3) and F(-2,1)
- Calculating the distance BC:
Putting values in above equation, we get:
- Calculating the distance CE:
Putting values in above equation, we get:
To calculate the perimeter of a rectangle, we use the equation:
....(1)
where,
l = length of the rectangle = BC = 5.66 units
b = breadth of the rectangle = CE = 4.47 units
Putting values in equation 1, we get:
Hence, the perimeter is about 20.26 units
